Bottle Company Case Study
Statistics MAT/300

As Manager of the Harley Bottle Company, I have been receiving complaints from customers on the quantity of product received when purchasing our sixteen ounces soda bottles. These complaints have caused my boss to worry and would like me to investigate the issue at hand. I will begin my investigation by instructing the employees to pull at random 30 bottles from all the shifts at the bottling plant. By pulling random containers from all shifts, I can eliminate the possibility of if being a human error. To start my investigation I begin by weighing the sample size of 30 bottles. The weight ranges between 14 oz. and 16.1oz., which lets be know there is a problem with our bottling consistence. For more detailed information to complete my investigation I must calculate the Mean, Median, and Standard Deviation of the sample size. * The Mean is the sum of the sample size in ounces divided by sample size. Based on the sample size of 30 bottles, there is a total of 446.1 ounces divided by the sample size of 30, gives is the mean of 14.87. = 14.87 * The Median is the data set middle number when the set is sorted in numerical order. Median of the 30 bottles is 14.8. * Standard deviation is the measure of how spread out the numbers is. To find the (Standard Deviation), you must find the square root of the variance. The is 0.5503.
The Harley Bottling Company is very optimistic of is bottling process. I will now construct the Confidence Interval of the ounces in the bottles at a 95%. The Confidence Interval describes the amount of the uncertainty associated with the sample estimate of the population parameter. By using the already discovered the information above I computed the Confidence Interval. 14.673 ≤ μ ≤ 15.067
My next course of action was to complete a hypothesis testing of the data…...

Battling Company Case Study

...Bottling Company Case Study Vincent Bacon Dr. Pamela Self MAT 300 Statistics December 14, 2013 Bottling Company Case Study Calculate the mean, median, and standard deviation for ounces in the bottles. To determine the mean, which is the statistical average of all numbers involved, we will add the number of ounces together and divide by the number of bottles, in this case 30. For the mean we get 446.1 / 30, for a mean of 14.9. The median, however, is the ‘middle’ number of the bottles ounces. Since we have an even number, it will be the average of the two middle numbers, which will give us a better perspective of the average than just the mean will. In this case it will be 14.8 + 14.8 / 2, which equals 14.8. The standard deviation is calculated to show how far apart the data can be. In the bottling case, after using the mean to get the variance, we divided by 30-1 to get a standard deviation of 0.55 (rounded down to two decimal places). Construct a 95% Confidence Interval for the ounces in the bottles. In order to construct a confidence interval, we need several statistics. The first is the sample mean, which is 14.9. Since we have selected a confidence interval of 95%, we need to find the margin of error to calculate our findings. Using the t-score model ( compute alpha, find the critical probability [.975], the degrees of freedom [999]) (StatTrek, 2013), we find that the critical value is 1.96. When we multiply this by the confidence......

A Case Study of Abc Company

...A Case Study of ABC Company COMM/215 Essentials of College Writing 8 May 2014 A Case Study of ABC Company What follows below is an analysis of the ABC Company’s hiring and training practices. In reviewing the events as described, many issues have surfaced regarding the assigned recruiter, Carl Robins and the human resources and training practices of the ABC Company. There are numerous examples of disorganization, lack of following through and areas of overlapping responsibilities, requiring a possible reorganization of the business itself. Although the Case Study does not specify, for the purposes of analysis it is assumed that there are separate Human Resources and Training Departments within the company, for, in today's business world, it would be difficult to imagine a company structure that did not include these two key departments. Initially, there appears to be a definite lack of coordination, planning and follow-through of the newly hired recruiter, Carl Robins. There are many incidents that demonstrate his lack of follow-through in the entire hiring and training processes. Many questions arise that deserve to be asked and examined. For example, 1) Why did he not immediately follow-through with the newly hired employees to ensure all required paperwork was properly and timely completed? 2) Did he assume that the Human Resource Department or Monica, the Operations Supervisor would follow-through with the scheduling of drug testing, physicals, etc. of......

The Bottling Company Case Study |

...| The Bottling Company Case Study | MAT300 (Statistics)Professor Pamela Self | | | 9/7/2014 | | Abstract In my research I find the mean, median, and standard deviations. These are simple calculations that can be done in Excel as long as you have the correct information. I was given the ounces of thirty bottles and had to find out whether the bottling companies were putting less than the advertised amount of liquid into the bottles. I believe the companies were putting enough in there but my results showed different. In my assignment, I had to find the mean, median, standard deviation, and confidence interval. I have inserted a spreadsheet to show my calculations. To find the mean I took the sum of ounces for all thirty bottles that were given (=average(B3:B32). To find the median I used the formula in Excel which is: =MEDIAN(B3:B32). To find the standard deviation, I used the formula in Excel as well which is: =STDEVA(B3:B32). The 95% confidence interval is +1.96 and -1.96. I took each bottle and added and subtracted the standard deviation from it to get my results. Majority of the bottles fell within the 95% confidence interval of 14.67 and 15.07. From my results, I was able to create a hypothesis that the claim of bottling companies are putting less than sixteen ounces in the bottle to be true. There can be many reasons the bottles are coming with less than sixteen ounces in them. One reason could be the types of machines that are being used are not......

Bottling Company Case Study

...Bottling Company Case Study Jason Otterbach Instructor: Agata Corobana Strayer University June 8, 2014 Imagine you are a manager at a major bottling company. Customers have begun to complain that the bottles of the brand of soda produced in your company contain less than the advertised sixteen (16) ounces of product. Your boss wants to solve the problem at hand and has asked you to investigate. You have your employees pull thirty (30) bottles off the line at random from all the shifts at the bottling plant. You ask your employees to measure the amount of soda there is in each bottle. A Confidence interval is a term used in inferential statistics that measures the probability that a population or sample parameter will be fall between two set values. The confidence interval can take any number of probabilities, with the most common being 95% or 99% (Investopedia.com, n.d.). To find the 95% confidence interval for the ounces in the bottles, we need to find the margin of error E. E =Z_C*(Ó/√(n) 446.1 / 30 = 14.87 x̄ = 14.87 n= 30 σ = 0.5503 E = (14.87 + 14.87) / 2 = 14.8 The 95% confidence interval for the ounces in the bottles can be written as x̄ ±E = 14.87- 0.2 and 14.87 + 0.2 = 14.67 ~ 15.07 In conclusion, with 95% confidence, the mean of the ounces in the bottles is between 14.67 ~ 15.07 ounces.

You may create and / or make all necessary assumptions needed for the completion of this assignment. In this assignment, you, in the role of a risk manager at Simply Green Products, will draft a document that is commonly used in the business world—a memorandum to your boss. Simply Green Products is a $10 million company that produces biodegradable packing materials that orchards use in the Shenandoah Valley to transport their apples, peaches, and pears nationwide. Biodegradable materials are more eco-friendly because they break down into the environment. Such packing materials are marketed under the name “SafePack,” which is heavily advertised in trade journals. Simply Green Products have had the name “SafePack” imprinted on all of their packing material since 2008; however, they never filed for either state or federal trademark protection. With the movement toward more eco-friendly agricultural production, the fact that such packing materials are biodegradable provides a primary marketing advantage over non-biodegradable competitors. The company president, Shep Howard, has recently become aware of several issues that may require referral to the company’s outside counsel.

Bottle Company Case Study

...I am a manger over a bottling company called Smith Bottling. I have been the manager with this company for the past 10 years and this is the first complaint of this magnitude and I want to ensure that the issue is proved and resolved. We have been getting complaints from customers that the 16 ounce bottles are less that advertised. We pride ourselves here on customer service and want to ensure all customers are receiving what they pay for and happy with their purchase. First step was to obtain samples to test. I asked a few employees to obtain 30 bottles (wanted a good range of sample). The initial weights of the samples taken for review were 14oz. and 16 oz. After taking these samples, I have to bring myself to the realization that there was in fact a problem with the bottling amount. I thought by calculating the Mean, Median and the Standard Deviation, I could come up with better numbers and provide a better detail to my investigation. The mean is the total of the samples divided by the actual number of samples that were taken. Since I took 30 bottles, and the total numbers of ounces were 446.1 this provides a mean of 14.87. The median is the middles number once all samples are sorted in numerical order. I figured the median to be 14.8. The standard deviation is the distance each number is from the next number. I had to find the square root of the variance giving me a number of 0.5503. Smith Bottling is hopeful of our process and wants to make sure......

That is no different than where I’m at as a manager of a bottling company. I want to make my customers happy and there have been complaints that our sodas are not meeting the labeled size of sixteen ounces. Customers are saying that there are less than sixteen ounces in our bottle. I plan to perform tests to see if we really do having a problem and if we do we need to correct the issue. For use to determine what is going on we collected a sample of bottles from all shifts at the plant for a total of 30 bottles. We calculated the amount of liquid in ounces of each bottle and recorded our date. We determined from the data gathered that out mean is 15.85 ounces, the mode was 16.21 ounces and the median was 15.99 ounces. From the data gathered we were then able to determine the standard deviation of the thirty bottles which was 0.66138 ounces. This information will allow us to see what our average is with the mean and from our average we are below the promised 16 ounces we promote. Then we look at our mode and it shows that our most commonly seen number is 16.21 ounces which tells our team that we have several bottles that are over 16 ounces. Once we achieve those numbers we construct a 95 percent......

...Whistler Corporation Case Study Ivana Cizmic BU502 Instructor: Dr. Peggy Bilbruck Southern States University 2016 Abstract This case study is about analyzing the Whistler Corporation business issues. The Whistler Corporation at some point had to make a very important business decision. The decision was about if the company should continue manufacturing operations in the US or not. The company had experience some serious problems with the domestic production in the US, where competing with companies that had their supplies imported from the east Asia become impossible. The Whistler Corporation hired a consulting company to solve these issues and also to help with manufacturing process. The corporation management had to make big decision in order to decide whether to make changes in general or if the products should have to be acquired offshore (Ellet, 2009). Whistler Company Case Study Analysis In 1983, Whistler Company was still small and it was in development. However, in that time the Whistler corp. was profitable and it was considered as one of the companies with the highest level of growth in the market. During the 80s, Whistler Corporation was the only company in the market that was making innovated radar detectors. In that period company made many new successful models, but with the rapid growth in business came some issues. The issues were shown thru some limitations in the process of production that was in need of new technology in order to make......
