At the 5% significance level, the null hypothesis of equal population variances is not rejected. At the 5% significance level, conclude that male managers have a higher salary, on average, than female managers. At the 10% significance level, conclude that male and female managers have different average salaries. ® F-Test for Equality of Variance 74649600 Variance: Male 55950400 Variance: Female 1.33 F 0.3774 p-value (one-tail) Two-sample t-test (Independent Groups) Male Female 75420 mean 78652 8640 42 7480 std. dev. 39 n 78 df 3232.00 difference (Male Female) 0 hypothesized difference 1.80 t 0.0379 p-value (one-tail) 0.0758 p-value (two-tal)
