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. Men Women 186 211 15,668.1 16,214.6 8,632.1 7,301.3 vviar are une riuir ana ailermauve Typoulesesr 2-2 H1 : 202 1 2 1 2 Identify the test statistic. Round to two decimal places as needed.)
