In this case, marginal revenue is a line starting at a price of $14 and intersecting the quantity axis at a value of Q = 3.5.

...Lonice’s Soda contain less than the advertised sixteen ounces of soda. Today I asked my employees to randomly pull thirty bottles off the lines at random from all the shifts at the Lonice’s bottling plant. After asking them to measure the amount of soda in each bottle we came up with the following data. (See attached spread sheet). To calculate the mean, median and standard deviation for the ounces in the bottles I first imported the data in excel. After importing the data I use the Data analysis function where I choose descriptive statistics. Once choosing descriptive statistics I clicked ok and input my data range. Afterward I selected summary statistics and press OK. The forwarding data was provided; the mean equaling 14.87, median equaling 14.8, standard deviation equaling 0.550. To construct a ninety-five confidence interval for the ounces in the bottles I use the following information. X equal to 14.87 which is the mean of the data from the bottles, n equal to 30, because of the amount of bottles we use, standard deviation equals zero point five five zero which was calculate with the data from the bottles. I use the formula [ ] which gave me the lower limit of 14.673 and an upper limit of 15.067. Finally I conducted a hypothesis test to verify if the claim that a bottle contains less than sixteen ounces is supported. With the claim that the bottles contains less than sixteen ounces my null hypothesis is mean greater than equal to sixteen and...

... Regression. Now you are ready to run regressions in EXCEL 1. Measuring Systematic Risk: Beta Coefficients The management of a publicly traded firm is interested in determining the firm’s cost of equity capital using the security market line (SML) version of the capital asset pricing model (CAPM). Management has measured the weekly returns for the market (S&P 500), its own stock, and the risk-free rate. The returns were annualized. The annualized percentage returns for each of the last 20 weeks are provided. 1a. See data in Excel file provided with this assignment. Using Excel, determine the excess rate of return on the firm’s stock (firm return less risk-free return) and the excess rate of return on the market (market return less the risk-free return). Put the two new variables (the excess return on the firm and the excess return on the market) that you have created into separate columns. (5...

...The equation of best fit, also known as the regression equation, is Credit Balance($) = 2591 + 403 Size. This means that for each 1 increase in household size that that credit balance increase by $403. 3. The coefficient of correlation is the square root of .566 which is .7523. This value being closer to one than to zero and being positive implies strong linear relationship between credit balance and size. It confirms that as credit balance increases, household size will also increase. 4. The coefficient of determination is .566. This value represents the proportion of the total sample variation of y, measured by the total sum of squares of deviations in the sample from the mean, can be explained by using credit balance to predict household size. This means that 56.6% of the sample variation credit balance (y) can be explained by using household size (x) in this straight line model. 5. The null hypothesis is that Beta1equals 0 and the alternative hypothesis is that Beta1 does not equal 0. The p-value is 0.000, which is less than 0.05. Therefore, the null hypothesis that Beta1 equals zero can be rejected. There is sufficient evidence that Beta1 does not equal zero. This shows that our regression model is useful, in that credit balance does depend on household size. 6. Based on my findings, credit balance will increase by $403 per 1 unit increase in the size of the household. This is confirmed by the regression model proving to be useful and both the coefficient of...

As you can see, the fan cart is set at a constant position of 2.0 meters away from the motion detector. Velocity and acceleration are zero as the cart is not moving. Region 2: A change in motion is occurring. As the cart begins to move, the position of the cart moves closer to the detector. Velocity and acceleration are at a negative slope because the direction is changed from no movement to movement. Region 3: The fan cart is moving at a constant speed and direction towards the detector. Slope for velocity becomes positive as the speed is now greater than zero. Acceleration is constant. Region 4: The fan cart has now moved to a closer position to the motion detector. Velocity and Acceleration is at zero because there is no movement. Regions of Graph 3: Region 1- The fan cart is at a constant position as it is not moving. Since the position is just less than 2 meters away from the detector, we know the fan cart is not directly in front of the motion detector. There is no acceleration. Region 2- The fan cart begins to gradually accelerate towards the motion detector. While the position remains...

...Summary There are many issues with this world, but I think the biggest one that affect everyone is hate. People are constantly hating on someone and putting people down because of their lifestyle choices. They are being abused for their religion, the people they like, their gender, and most commonly the way they look/ their weight. People become self-conscious because of this, just because you do not have the ideal body type you can be treated as a lesser person. Someone always has something to say, you are either too fat, too skinny, or look too butch because you have muscles. People need to stop worrying about the ideal body image and start working on being healthy. Introduction In today’s society, people have a big misconception on the...

This background information will provide a summary of professional standards and guidance directly related to APRs. First and foremost, every auditor must follow the standards called the Generally Accepted Auditing Standards (GAAS) which are set by the Public Company Accounting Oversight Board (PCAOB). Important sections within the standards required to know include: Independence, Consideration of Fraud in a Financial Statement Audit, and Communications about Control Deficiencies in Financial Statements, which includes nine rules that deal with identifying and reporting deficiencies found in financial statements. In the second part of our report, we prepared basic ARP’s and identified some key red flags for the Chevron Company. To access client viability, we used vertical and horizontal analysis, where we found...

It is probably the only truly raw, organic, natural, low calorie, and low glycemic sweetener available. Sugar alcohols tend to have very low GIs. In particular Erythritol has a GI of only 1, and it is a safe low calorie sweetener that occurs naturally in some fruits and mushrooms. While many of the other sugar alcohols also have low GIs they can have side effects such as abdominal cramping if taken in even moderate quantities. Both the natural zero calorie...
