Let s suppose that you work in the quality control department for the M&M s/Mars Company. You have been tasked with reviewing product consistency regarding the packaging of plain M&M s candy. Your job is to determine if the number of blue green brown orange and yellow M&M s in each bag is relatively equal. Obviously not every bag will contain the exact same number of M&M s divided into equal quantities. However as part of your quality control responsibilities you want to determine if there is a significant difference in the number of colors in each bag. After all you don t want customers to open a bag and only receive primarily one or two colors. You could use a one variable chi-square test to analyze your research question: is the number of blue green brown orange and yellow M&M s significantly different?Your stated null and alternative hypotheses would look like this:Ho: There is no significant difference between the number of blue green brown orange and yellow M&M s per bag.H1: There is a significant difference between the number of blue green brown orange and yellow M&M s per bag.Next we would move through the steps required to complete the chi-square test.1. How would you conduct this analysis? What are the steps that we must follow?
