Periodically, Merill Lynch customers are asked to evaluate Merrill Lynch financial consultants and services. Higher ratings on the client satisfaction survey indicate better service with 7 the maximum service rating. Independent samples of service ratings for two financial consultants are summarized here. Consultant A has 10 years of experience, whereas consultant B has 1 year of experience. Use a = 0.05 and test to see whether the consultant with more experience has the higher population mean service rating. Round degrees of freedom to previous whole number. Excel File: data10-17.xlsx Consultant A Consultant B T = 16 Tg = 10 1 = 6.82 E = 6.25 81 = 0.64 82 = 0.75 a. State the null and alternative hypotheses. Họ: 41 - 2 is less than or equal to 0 Ha: 41 - 2 is greater than o b. Compute the value of the test statistic. (to 2 decimals) c. What is the p-value? Use Table 2 from Appendix B to find the values that bound the test statistic. 0.025
