have equal amounts i.e. In the case of bags of M&M's you would be
saying that there is an equal number of each color in each bag
There are an average of 35 peanut M & Ms in each package and there are 6 colors
35/6 =5.8
2. A known statistic you are comparing your results to./ ie. We compare the
number of M&M's, by color, in a sample of bags to the number of each
color the company claims on its website.
Assuming a bag of 35 then by percent it would be 9 blue, 8 orange, 4 green, 5 yellow, 5
red and 4 blue(roughly)
