Question

The accompanying table gives results from a study of words spoken in a day by men and women. Assume that both samples are independent simple random samples from populations having normal distributions. Use a 0.05 significance level to test the claim that the numbers of words spoken in a day by men vary more than the numbers of words spoken in a day by women. What are the null and alternative hypotheses? A. H_0: sigma^2_1 = sigma^2_2 H_1: sigma^2_1 sigma^2_2 Identify the test statistic. F = (Round to two decimal places as need.) Use technology to identify the P-value. The P-value is. (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? A. Fail to reject H_0. There is sufficient evidence to support the claim that the numbers of words spok

Explanation / Answer

here for null and alternate hypothesis: option D is correct

F=(8632.9/7301.5)2 =1.3979

p value =0.0096~0.010

conclusion : reject Ho: there is sufficient... option B
