M & M Project Essay Example

Abstract The purpose of this paper is to provide a written report of the five part M&M project. Part one was sampling. We were to purchase 3 bags of M&M and record the color counts of each bag in an Excel spread sheet. For part two we calculated the sample proportions for each color, the mean number of candies per1.69oz bag, created a histogram for the number of candies per bag, use Excel to compute the descriptive statistics for the total number of candies per bag and summarize the information. In part three we located the 95% confidence interval for the proportion of blue, orange, green, yellow, red and brown. For part four we tested claims for percentages of each color. In the final part of the project we tested the hypothesis that the population proportions of red and brown were equal. This report will explain what was done, present the results and provide an analysis of what was found.
Title
This reported is presented on the statistical data investigated on M&Ms. This report contains information on the average number of candies per bag and sample proportions. We have conducted tests to ensure that our proportions, going into each bag of m&ms, are on target. We have also conducted hypothesis testing to ensure that our average number of m&ms per bag is on target as well.
Project Part 1: Sampling Method The first assignment was to collect three 1.69oz bags of plain M&Ms from different stores. We were to count each other color in each bag and record the information on a spread sheet in Excel. The students’ personal samplings were combined to create the full random sample.
Project Part 2: Method, Analysis, Results For this portion of the report we calculated the sample proportions for each color and the mean, or average number of candies per bag, number of candies per 1.69oz bag. We also created a histogram for the number of candies per bag and summarized the total number of calculated proportions. The sample standard deviation was also calculated.
