Abstract
This paper is about the color proportion of each bag of M&Ms®. Now even though the factory has a claim of the each bag being grouped off into a certain percentage of each color, the results are not always the same. In fact, I will show through random selection process that M&Ms® brand candies each have a different number of candies in the bag and from that a different percentage of each color represented. I will use different statistical formulas and hypotheses to state my claim and give evidence as it relates to the results of the claim. This study was conducted in 5 different parts, by a total of 74 people, each person obtaining bags of M&Ms® in the same manner but in different locations.

Title
The purpose of this report is to examine the packaging process for plain 1.69 ounce bags of M&Ms®.
.
Part 1
For the first part of this project I went to three different stores, (Publix, Piggly Wiggly, and Trinity Gift Shop) and purchased a bag of plain 1.69oz M&Ms® at each store. Purchasing a single bag at a random store assured the process of obtaining a true random sample. After purchasing each bag of M&Ms®, I separated each bag by color and charted the results into an Excel spreadsheet:
  | Blue | Orange | Green | Yellow | Red | Brown | Num. of Candies in Bag |
bag 1 | 2 | 14 | 12 | 8 | 10 | 11 | 57 |
bag 2 | 7 | 20 | 7 | 7 | 9 | 9 | 59 |
bag 3 | 10 | 4 | 6 | 7 | 16 | 13 | 56 |
The data was then combined with 73 other random bags of M&Ms®, whose data were obtained and recorded in the same fashion.

Part 2
For part two I will be using the data from the combined M&Ms® for a total of 74 bags.
879 | 854 | 724 | 562 | 558 | 582 | 4156 | Total number of candies sampled |
Blue     orange     green yellow       red       brown      
I will present calculations of the sample mean for the number of candies per...
