Question

The researchers using red and blue backgrounds are also conducting trials to investigate the effects of color on the accuracy of recall. Subjects are given 36 words on a screen for two minutes, then asked to recall as many of the words as they could after waiting for twenty minutes. Results are below. Use a 0.05 significance level to test the claim that variation of scores is the same with the red and blue background.

Red Background	n = 35	mean = 15.89	s = 5.90
Blue Background	n = 36	mean = 12.31	s = 5.48

Group of answer choices

A. F = 1.1592 There is not sufficient evidence to warrant rejection of the claim.

B. F = 1.152, There is sufficient evidence to reject the claim that the score variation is the same regardless of background.

C. F = 1.8752 There is not sufficient evidence to warrant rejection of the claim.

D. F = 1.8752 There is sufficient evidence to warrant rejection of the claim

Answer 1
