The following null and alternative hypotheses are given: Ho : u = 1100 H :4> 1100 where the standard deviation a = 48, and the sample size n= 26. Part A Write the expression of the transformation from x-values to z-values: Use mu for the mean, signa for the standard deviation, o X for the randon variable, X n for the sample size, n sqrt() for the square roots. Part B Write the critical z-value of standard normal distribution (from spreadsheet or look-up tables): For this test take a = 0.06. Part C Calculate the upper and lower x-values corresponding to critical z-values, za and Za. respectively: Ierit,U

Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?
