Periodically, customers of a financial services company are asked to evaluate the company's 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. Consultant A n₁ = 16 X₁ = 6.84 $1 = 0.69 Consultant B n₂ = 10 x₂ = 6.29 $2 = 0.75 (a) State the null and alternative hypotheses.
