Answer:
The null and alternative hypotheses are:
Under the null hypothesis, the test statistic is:
Therefore, the test-statistic is
Now the F critical value at 0.02 significance level for df1 = 10- 1 =9 and df2 = 16 - 1 =15 is:
Since F statistic is greater than the F critical value, we therefore, reject the null hypothesis and conclude that there is sufficient evidence to support the claim that there is a difference in the variation in the listening times for men and women.
