3. Suppose you are testing Ho: u = 73 versus H1: u 60 The sample is large (n = 53) and the variance, o', is known. (a) Should you use z or t when finding a critical region for this scenario? (b) Find the critical value(s) corresponding to o = 0.033. (c) State the critical region. (d) You find that the test statistic value is -1.98. Based on your critical region, what decision do you make regarding the null hypothesis (i.e. do you Reject Ho or Do Not Reject Ho)? (e) State your conclusion
