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.

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. Fail to reject Ho. There is sufficient evidence to support the claim that the numbers of words spoken O B. Fail to reject Ho. There is insufficient evidence to support the claim that the numbers of words
in a day by men vary more than the numbers of words spoken in a day by women.
OC. Reject Ho. There is sufficient evidence to support the claim that the numbers of words spoken in a
spoken in a day by men vary more than
numbers of words spoken in a day by women.
O D. 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.
