Use a 0.05 Signicance level to test the claim that the samples are from populations with the same standard deviation. Assume that both samples are Independent simple random samples from populations having normal distributions. Does the background color appear to have an effect on the variation of word recall scores? ' n i 5 Red Background 35 15.98 5.96 1 Blue Background 36 12.97 5.44 I 11 Identify the test statistic. 1 F = D (Round to two decimal places as needed.) Use technology to identify the P-value. The Pvalue is D. (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? . O A. Fail to reject H0.
