Running head: M&M PROJECT REPORT Abstract This paper examines the proportion of M&M candies through the random sampling of 156 bags. After reading this paper one should have a better understanding of the process that accompanies packaging M&M candies. The bags used in the experiments were taken from different stores to help ensure a true sample of all the 1.69 oz of plain M&M candies. Introduction: Purpose of Report The purpose of this report is to examine the five project parts of an M&M analysis and examine a method for quality control. The parts of this project included using random sampling to gather data on the number of colored M&M candies, the sample proportion and sample mean, constructing a 95% confidence interval and testing claims of M&M candies. By the end of this report a better understanding of the methods behind packing M&M candies should be gained. Project Part 1: Sampling Method To begin the M&M analysis a random sample of three 1.69oz bags of plain M&M candies where purchase by each individual students from three different stores. A random sample ensures that every member of the population has a chance to be selected. The population in statistics refers to the “collection of all outcomes, responses, measurements, or counts that are of interest (Larson, & Farber, 2009).” Buying bags from different stores assures a true sample of the population of all 1.69 oz bags of plain M&M candies. Once bags were purchased students were instructed to open each bag individually and record the number of candies of each color within the bags. This information was then entered into an excel spreadsheet and separated by individual bags. These individual results were then combined together into a single data set. Data refers to the “information coming from observations, counts, measurements, or responses
