At Western University the historical mean of scholarship examination scores for freshmanapplications is 900. A historical population standard deviation = 180 is assumed known.Each year, the assistant dean uses a sample of applications to determine whether the meanexamination score for the new freshman applications has changed.a. State the hypotheses.Ho:0:equal to 900Ha: not equal to 900b. What is the 95% confidence interval estimate of the population mean examination score if asample of 200 applications provided a sample mean of = 935 (to the nearest wholenumber)?c. Use the confidence interval to conduct a hypothesis test. Using a = 0.05, can the assistantdean conclude that the mean examination score for the new freshman applications haschanged?- Select your answer -d. What is the p-value (to 4 decimals)? (Use Table 1 from Appendix B.)
