Words were displayed on a computer screen with background colors of red and blue. Results from scores on a test of word recall are given below. Use a 0.05 significance 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 Red Background Blue Background 34 15.62 12.78 5.92 37 5.48 What are the null and alternative hypotheses? OA Hoi o = OD. Ho: o =o Identify the test statistic. F= 1.17 (Round to two decimal places as needed.) Use technology to identify the P-value. The P-value is (Round to three decimal places as needed.)
