question 42

Essay

MARS claims that Skittles candies should be comprised of 30% purple, 10% orange, and 20% should be red, yellow, and green. Business students count a large bag of Skittles and find 265 red, 279 purple, 303 yellow, 271 green, and 212 orange candies.
A) Set up the competing hypotheses to test if at least one proportion is different than the value claimed by MARS.
B) Calculate the value of the test statistic and determine the degrees of freedom.
C) Compute the p-value. Does the evidence suggest that at least one proportion is different from the claimed value at the 5% significance level?
