HW8: Problem 5 Previous Problem Problem List Next Problem (1 point) Randomly selected students were given five seconds to estimate the value of a product of numbers with the results shown below. Estimates from students given 1 x 2 x 3 X 4 X 5 X 6 X 7 X 8: 1500, 10000, 842, 40320, 500, 2000, 4000, 6000, 175, 1000 Estimates from students given 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1: 500, 42000, 1500, 300, 1500, 49000, 2000, 400, 225, 3000 Use a 0.05 significance level to test the following claims: (a) Claim: the two populations have equal variances. The test statistic is The larger critical value is The conclusion is OA. There is not sufficient evidence to reject the claim that the two populations have equal variances. (So, we can assume the variances are equal.) OB. There is sufficient evidence to reject the claim that the two populations have equal variances. (So, we can assume the variances are unequal.) (b) Claim: the two populations have the same mean. The test statistic is The positive critical value is The negative critical value is The conclusion is OA. There is not sufficient evidence to reject the claim that the two populations have the same mean.
