Periodically, Merrill Lynch customers are asked to evaluate Merrill Lynch financial consultants and services on a 7-point scale (7 is the maximum). You ar a manager with two consultants you are trying to compare. Consultant A has 10 years of experience, whereas consultant B has 1 year of experience. You want to test the claim that the consultant with more experience has the higher mear service rating. So, you collect independent samples of service ratings for these two financial consultants. Consultant A has 25 surveys with a mean of 6.48 and standard deviation of 0.4: Consultant B has 28 surveys with a mean of 6.31 and standard deviation of 0.42 You wish to test the claim at a significance level of a=0.10 Ho: H1 – µ2 = 0 Ha: H1 – H2 > 0 (In this setup, Consultant A is sample 1 and Consultant B is sample 2) a) Find the test statistic. b) Find the p-value c) State the conclusion (in the context of the problem).
