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. n X S Men Women 185 211 15,667.8 16,215.3 8,632.7 7,301.6 What are the null and alternative hypotheses? OA. Ho₂:0² #0²₂2 B. H₂:0² = 0²/2 H₁:0² > 0² H₁ : 0 ²₁2 = 0²/2 OC. H₂ : 0 ²₁2 = 0²/2 OD. H₂:0² = 0²/22 H₁:0² <0² H₁: : 0² / ± 0²/2 Identify the test statistic. F= (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.) What is the conclusion for this hypothesis test? O A. Reject Ho. There is insufficient evidence to support 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. B. Reject Ho. There is sufficient evidence to support 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. O C. Fail to reject Hỏ.
