M&M Project at Masterfoods USA
M & M Project Masterfoods USA put together a team to review the color a proportion of the M&M’s being placed in each 1.69 bag. To ensure that a random sample was obtained, each of the 20 members on the team acquired a bag of M&M’s from three different store locations. Each part of the project utilized the M&M’s obtained to determine if the color proportions are what the company expected to be in the bags. Additionally, the team identified a couple of process that could assist the company in getting the proportions they expect.
Project Part 1: Sampling Method In part one of the M&M Project, the requirements were to go to three different stores to purchase three bags of 1.69 oz. M&M’s. Once the three bags were obtained, the students were to open the bags and count the number of each M&M in each color category; blue, orange, green, yellow, red and brown. The number counts of each color category for each bag were recorded in a spreadsheet. Since each project team member acquired three bags, we then took the information from the personal samples of each student and combined with others to create the full random sample.
Project Part 2: Method, Analysis, Results In part two of the M&M exercise, the project team took the full random sample and calculated the total each of the colors and calculated the sample proportion of the candies. With sixty (60) bags in total, the total results were blue - 689, orange - 765, green - 586, yellow - 458, red - 422, and brown -409. The sample proportion was obtained by taking the total of one color and dividing by the total of all colors (3329). The total sample proportion for each color was blue .207, orange - .2298, green -.176, yellow - .1376, red - .1268, and brown - .1229. In addition to totaling the candies and calculating the sample proportion of each color, a histogram was created. The histogram is a graphical representation of the probability distribution of a given variable depicting the

The next step in solving the problem is to construct a 95% confidence interval for the average amount of the company’s 16-ounce bottles. The confidence interval was constructed by drawing a normal distribution with c = 95%, a = 0.050, and Zc = 0.025. The Zc value was entered into the Z◘ (z box) function in the Aleks calculator that resulted in a Z score of +1.96 and -1.96. We calculate the standard error (SE) by dividing the s by the Square root of n which is the sample size. The margin of error is calculated by multiplying the z score = 1.96 by the std. dev. = 0.5503/the square root of n = 5.4772. The result is a 0.020 margin of error. The margin of error is added to and subtracted from the mean to give two numbers the lower and upper values. The lower value is 14.85 and the upper value is 14.89. So, we can say that with 95% confidence the mean of the sample is between 14.85 and 14.89.…

Aspect 3: In each of our labs, we made mistakes, so not all of our results came out 100% accurate. In our first lab, we could have improved our results by using a more accurate scale or being more careful when attempting to release the gases. In the second lab, our ratios may have been off because the crème or the cookie was still attached to the other. We could fix this by freezing the cookies before the lab to prevent the crème from sticking to the cookies. In the final lab, my partner and I came closer to the correct percentage, of 39.17%, than our class’ average did. The reason our percentage could have been off may have been because we did not heat the material long…
