Abstract

This paper shows the true proportions of M&M candies through the random sampling of

3 different bags of plain M&M 1.69oz bag of candy bought from three different stores.

I believed one will be able to determine data analysis and how it works as it relates to

our class project.

Introduction

The rationale of writing this paper is to show how statistics data analysis works. Statistics

as we learned, is the practice of collecting, organizing, analyzing and interpreting data to

make decisions. The two types of data used in the project are sampling and proportions.

The methods used can be used by any professional or in any occupation. It can be used to

determine the standard deviation, mean of any data among others.

Part 1

In part one, each student was asked to take a tally of the 3 bags of candies bought from

three different stores. And then we were asked to count the totals of each color in all 3

bags.

Part 2

We used the excel data provided to complete the assignment. We looked at the data from

two perspectives” color and proportions and the number of candies per bag. For the color

proportion; we used the total for each color divided but the total number of candies

sampled. As for the number of candies per bag, we use the data in the number candies in

bag column. We used the total number of candies per bag divided by the total candies to

arrive at the color proportion.

Blue Orange Green Yellow Red Brown

757 743 610 393 421 418

0.2265 0.2223 0.1825 0.1176 0.126 0.1251

Then we were made to calculate the sample mean number of candies per bag.

In another sheet within the workbook we used, we created a histogram for the number of...

...M&M Project Math 336 (1) Buy a packet of regular size M&M's. Record the frequency of each color and then transfer this information to a bar chart and a pie chart. (2) Represent the number of M&M's per packet on a histogram using all of the class data. Is your histogram normally distributed? Check using the empirical rule. Also choose your favorite color and draw a histogram of the number of M&M’s of that color per packet based on class data. Draw a box-plot of the total number of data in a packet based on class data. (3) There are numerous hypothesis tests that can be done. Obtain the mean number of M&M's per packet for the whole class. Consider as a null hypothesize that the actual number of M&M's in your packet is the actual number of M&M's per packet as intended by the manufacturers. Test this hypothesis using the sample data from the class. Comment on the difference between a type I and type II error in this context. (NOTE: Be careful in the choice of your sample size.) (4) Test the assumption that on average there are the same proportion of red and yellow M&M’s per packet. (5) Devise a test to see if there are the same number of red M&M’s per packet. (6) Another obvious test would be to test the proportion of colors present. Intuitively, we might expect each color to occur with the same probability p (Null Hypothesis) but a quick inspection of data suggests this is not so. Test this hypothesis. (5) Perhaps the manufacturers do not stick to......

...M & M’s Project Erica Warren Strayer University Abstract Over a short time frame of approximately 11 weeks, data was collected and recorded, on the number of candies of each color, within several bags of 1.69 ounces of plain M & M’s. The purpose of this experiment was to examine the packaging process for these plain M & M candies. A random sample on several bags of 1.69 ounces of M & M’s was collected and the population data was produced. The main focus of this project is the color proportions and the number of candies per bag. Calculations were done for the sample proportions, mean, and sample mean of the number of candies per bag. An excel spreadsheet was created to show a histogram for the number of candies as well as a descriptive statistics which summarized other information. Confidence intervals, for the proportion of each color as well as the mean number of candies, were constructed at 95%. Several hypotheses test, along with conclusions was calculated for the color proportions to test Master foods USA statements. The final step was to compare the red and brown candies and test the hypotheses to see if they were equal.

...Part 1 First to get started with the project three 1.69 ounce bags of plain M&M’s were purchased from Walgreens, Rite-Aid and Dollar General. These bags will help with taking a sample of the population that is produced. Purchasing the bags from three different stores will help with the results of the project being meaningful because it is assured that the samples will be truly random. Random sampling is when all members of a group have an equal and independent chance of being selected. Next each individual bag of candy was opened and counted. When counting the candies were put into groups based on their color (blue, orange, green, yellow, red and brown) and the results were recorded on a spreadsheet. Once every bag was counted the findings were added up to find the total number of candies within each of the three 1.69 ounce bags of plain M&M’s. The findings were as followed: Bag One had 54 candies, Bag Two had 57 candies and Bag Three had 56 candies. Part 2 For this part of the project all of the data findings from the class were combined into one class data set. The data focused on the color proportions and the number of candies per bag. The information that was used for the color proportions is the total for each color and the total number of candies sampled. The data in the number candies in bag column was used for the number of candies per bag. First the sample proportions for each of the colors were calculated. A sample proportion is the number of individuals in......

...Excel Project Report Introduction: This project report is about the project we did on M&Ms. My hypothesis for this project is that bags of equal weight should have the same amount of candies in it. All the colors aren’t represented equally because there are 6 different colors so there must be more of that color in each bag. The color distribution doesn’t remain constant because the little bag will have less candies and the bigger bag will have more candies for each color. Data Collection: This project we are doing is on M&Ms. We opened the mini bags of M&Ms and recorded how many of each color there were and recorded it in the table under bag1. Then we went to 5 other peoples M&Ms and recorded how much M&Ms were there for each color and recorded those under bags 2, 3, 4, 5, and 6. Then I put that information in 3 different graphs.

...Short Essay Assignment # 2 Summary of #39 The world’s water challenge: Erik R. Peterson and Rachel A. Posner Deborah Phillpotts Professor Beth Stewart SOC300: Sociology of Developing Countries June 12, 2011 Article 39: The World’s Water Challenge: Erik R. Patterson & Rachel Posner Summary of Article This article was about The world’s water challenge. It addressed the dimensions and features that contribute to the world’s water crisis. According to the article “These factors suggest that even at current levels of global population, resource consumption, and economic activity, we may have already passed the threshold of water sustainability” (Griffiths, 2011) . So basically globally we are running out of water. Also the demand for water is so high and there is an insufficient amount of water supply to meet this. The dimensions of that the water challenges will affect include: healthcare, politics, our social lives, the economy, because the water supply is not sufficient and not easily sustained. This article also discussed the changes that are necessary to handle the challenge of shrinking water assets, the changes that I found very useful to implement are first and foremost educating the public about the water crisis, the government investing money into finding means to preserve the water supply we have today. There has to be more precautions taken when it comes to the ecosystems, even though it is inconceivable to maintain the water supply a stand has...
