4. Suppose you are testing Ho: µ = 50 versus H1: µ > 50 The sample is large (n = 68) and the variance, ơ², 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 a = 0.047. (c) State the critical region. (d) You find that the test statistic value is +1.87. 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.
