_ A B C Total

1 15 30 45 90

2 35 35 40 110

Total 50 65 85 200

a. Compute the expected frequencies for each cell. (Please Fill in the Blanks)

A B C

1 ___? ___? ___?

2 ___? ___? ___?

(Type integers or decimals.)

b. Compute 2STAT. Is it significant at =0.01?

Set up the null and alternative hypotheses to test. (Choose the correct answer below)

A. H0: Not all j are equal (where j =1, 2)

H1: 1 = 2

B. H0: 1 = 2

H1: Not all j are equal (where j =1, 2)

C. H0: Not all j are equal (where j =A, B, C)

H1: A = B = C

D. H0: A = B = C

H1: Not all j are equal (where j =A, B, C)

Compute 2STAT.

2STAT = ___? (Round to three decimal places as needed.)

Find the p-value.

p-value = ___? (Round to three decimal places as needed.)

Is 2STAT significant at =0.01? (Choose Below)

A. No, because the p-value is greater than or equal to the level of significance.

B. Yes, because the p-value is less than the level of significance.

C. Yes, because the p-value is greater than or equal to the level of significance.

D. No, because the p-value is less than the level of significance.

(a)

(b) Option D

2 = 6.746. Not significant.

p- value = 0.034

(c)

A B C 1 22.5 29.25 38.25 2 27.5 35.75 46.75
