According to the manufacturer of M&Ms, 13% of the plain M&Ms in a bag should be brown, 14% yellow, 13% red, 24% blue, 20% orange, and
16% green. A student randomly selected a bag of plain M&Ms. He counted the number of M&Ms of each color and obtained the results shown in
the table. Test whether plain M&Ms follow the distribution stated by the manufacturer at the a = 0.05 level of significance.
E Click the icon to view the table.
Determine the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: The distribution of colors is not the same as stated by the manufacturer.
H: The distribution of colors is the same as stated by the manufacturer.
O B. Hn: The distribution of colors is at most as uniform as stated by the manufacturer.
H1: The distribution of colors is more uniform than stated by the manufacturer.
O C. Hp: The distribution of colors is at least as uniform as stated by the manufacturer.
H,: The distribution of colors is less uniform than stated by the manufacturer.
O D. Ho: The distribution of colors is the same as stated by the manufacturer.
H4: The distribution of colors is not the same as stated by the manufacturer.
Compute the expected counts for each color.
(Round to two decimal places as needed.)
