You may need to use the appropriate technology to answer this question. 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 Consultant B = 16 x₁ = 6.81 $1 <=0.64 7₂ = 10 x₂ = 6.28 = 0.75 $₂=1 (a) State the null and alternative hypotheses. o Hoi khi thay 50 Hồ khi thu 20 OHH₁-H₂0 H₂: H₁ - H₂ = 0 OHO: H₂-H₂ ≤0 H :H1 - Hz = 0 o Hoi thi - thy > 0 H :H1-H250 |O Hot - t2=0 Ha: H1 -H2 +0 (b) Compute the value of the test statistic. (Round your answer to three decimal places.) 1.852 x You may have rounded in the wrong direction. (c) What is the p-value? (Round your answer to four decimal places.) p-value = 0.9587 x You may have found the complement of the desired probability.
