Question 10 (10 points) We took from a database of a large service company, a random sample of 49 employees at "middle management" level. Employees have been grouped by gender. Following a discussion with an executive from the human resources department stating that the salary of male executives is higher than that of females, we want to compare the average annual salary according to the gender of the employee. Using a significance level of 1%, we obtain the following Excel report: Test of equality of expectations for two populations of equal variances Male Feminine Average 41739.0 40838.8 Variance 1011337.778 2675486.16 Comments 28 21 Weighted variance Hypothetical difference in means Degree of freedom t-statistic P(T
