4.Use StatCrunch to solve the following:

Mars, Inc. claims that its M&M plain candies are distributed with the following color percentages: 16% green, 20% orange, 14% yellow, 24% blue, 13% red and 13% brown. Refer to the dataset of a sample of 100 candies to test the claim that the color distribution is as claimed by Mars, Inc. Use a 0.05 significance level.

a. Equal Frequency or Unequal Frequency?

b. Find the observed frequencies and the expected frequencies.
