8. To investigate possible gender discrimination in a firm, a sample of 100 men and 64women with similar job descriptions are selected at random. A summary of the resultingmonthly salary follows:MenWomenAverage Salary Y$3,100$2,900Standard Deviation(Sy)$200$320n10064a) What do these data suggest about wage differences in the firm? Do they representstatistically significant evidence that wages of men and women are different? (Toanswer this question, first state the null hypothesis; second compute the relevant t-statistic; and finally give an estimate of the p-value).b) Do these data suggest that the firm is guilty of gender discrimination in itscompensation policies? Explain.

The given information is,Average Salary Standard deviation Men$3100$200100Women$2900$32064
