In a move that shocked candy traditionalists, the M&M/Mars Company recently replaced the tan M&M’s with blue ones. More than ten million people had voted in an election to select the new color. On learning of the change, one concerned consumer counted the number of each color appearing in three pounds of M&M’s (55). His tally, shown in the following table, suggests that not all the colors appear equally often—blues, in particular, are decidedly less common than browns. According to an M&M/Mars spokesperson, there are actually three frequencies associated with the six colors: 30% of M&M’s are brown, yellow and red each account for 20%, and orange, blue, and green each occur 10% of the time. Test at theα=0.05 level of significance the hypothesis that the consumer’s data are consistent with the company’s stated intentions.
