M&M Project Report - Research Paper Example

? M&M Project Report Strayer The objective of this report is to write in a layman’s language, all the parts involved in theM&M project. The report will lead to an explanation of what was done in each part, as well as the result. Presentation of the data and the results will be on an excel worksheet. The first part will explain the sampling technique. Here, 135 bags and 7563 number of M&M candies were sampled and the color counts recorded in an excel worksheet. The number of candies per bag and the color proportions will be established and analyzed using excel tools in part two. Part three will involves analysis through construction of confidence interval to find out the distribution of candies per bag as well as the proportion for each color, and then recording of the results in an excel worksheet. Different claims of color proportions will be tested in the fourth part. Finally, the claim there is no difference between the number of brown and red candies will be tested in part five. Introduction: M&M Project Report The purpose of this report is to explain what was done in each part of the M&M project, as well as analyzing the results. In addition, the report will lead to investigation of quality control. The five parts of the project included sampling method, the sample mean and proportion, testing of different M&M candies’ claims, and using 95% confidence interval to do testing. In the end, the report will lead to a better understanding of the process and methods of packaging M&M candies. Part 1 135 bags of 1.69oz M&M candies were randomly obtained from different stores. A random sample was used to make sure that the sample was a true representative of the entire population. The population here means a collection of all the subjects that are to be studied – all the M&M candies for that matter. Different colors in each bag were counted and recorded in an excel work sheet. Student’s personal sampling was conducted alongside other methods to ensure full random samples (Smith, 2003). Part 2  This part involves calculation and analysis of the number of candies per bag and the color proportions. The color proportion will be determined using the total number of candies that have been sampled, as well as the total for each color. On the other hand, the number of candies per bag will use the data in the bag column. To obtain the proportion for any color, the number of candies for that particular color will be divided by the total number of candies. A separate excel sheet will be used to create a histogram for the number of candies per bag. The descriptive statistics for the total number of candies per bag will be computed in another sheet. The summary of all the important information will be made in another worksheet titled “Part 2 Summary." The descriptive statistics and the summary were as follows: Table 1: Descriptive statistics Num. of Candies in Bag   Mean 56.02222 Read More
