The Packaging Process of the M&m Candy

The Packaging Process of the M&M Candy

The purpose of this report is to provide a written report of the five part M&M project. In part one, we focused on sampling whereas each class member purchased a 1.69 oz bag of plain M&Ms randomly from 3 different retailers and recorded the color of each on to an Excel spread sheet. The data was then collected and combined in order to produce one class data set and in part two, we calculated the sample proportions of each color along with producing the mean number candies per 1.69 oz bag. An excel spreadsheet was used to create a histogram for the number of candies per bag and also to compute descriptive statistics, which included data such as sample mean, sample standard deviation, median, mode all for the number of candies per bag as well. In part three, a 95% confidence interval for each color proportion was determined and in part four, claims were tested for percentages of each color proportions. And in the final part of the project, is where a hypothesis was tested to see if the color proportions Red and Brown were equal to one another. The report will explain what was done, present results and provide applicable analysis of what was found.

Part 1

Researchers were responsible for collecting three 1.69 oz bags of plain M&M candies from different store locations in order to participate in the study. In order for the results to be meaningful, the candies were randomly selected from each display which assured a true random sample was being produced. It was not necessary to keep track of which bag came from which location. Each researcher opened each one of their M&Ms bag individually and recorded the number of candies of each. A sample of the population of all 1.69 oz bags of plain M&M candy purchased by the students were combined together in order to create one class data set. The combined class data
