2. Do the salaries of entry level data analysts and entry level marketing associates differ? Past studies suggest that the population standard deviation for entry level data analysts' salary is 4500 and the population standard deviation for entry level marketing Associates' salary is 4000. Let a = 0.05 You have collected a random sample and have obtained the following results: Entry level data analysts Entry level Marketing Associate 40 55 53 527 51 945 a) Formulate the hypotheses for this problem. b) Show the formula for the test statistic, substitute your values into the formula and compute the test statistic. c) Using either the p-value approach or the critical value approach, test the hypotheses. (You must report the p-value or critical value you found using tables or excel. If using excel, report the value to a minimum of 4 decimal places.) d) What is your conclusion? (Do not only say that you reject, or you do not reject the null hypothesis. Relate your conclusion to the question)
