3. Suppose you are testing Họ: µ = 13 versus H1: µ 7 13. The sample is small (n = 12) and the data come from a normal population. The variance, o², is unknown. (a) Should you use z or t when finding a critical region for this scenario? (b) Find the critical value(s) corresponding to a = 0.07. (c) State the critical region. (d) You find that the test statistic value is -2.103. 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.
