Skittles Statistics teacher Jason Molasky contacted Mars, Inc., to ask about the color distribution for Skittles candies. Here is an excerpt from the response he received: “The original flavour blend for the SKITTLES BITE SIZE CANDIES is lemon, lime, orange, strawberry and grape. They were chosen as a result of consumer preference tests, we conducted. The flavour blend is 20 percent of each flavour.” (a) State appropriate hypotheses for a significance test of the company’s claim.
(b) Find the expected counts for a bag of Skittles with 60 candies.
(c) How large a c2 statistic would you need to have sig-nificant evidence against the company’s claim at the a = 0.05 level? At the a = 0.01 level?
(d) Create a set of observed counts for a bag with 60 candies that gives a P-value between 0.01 and 0.05. Show the calculation of your chi-square statistic.
