Answer E et D

2. Suppose you are testing \( H_0: \mu = 47 \) versus \( H_1: \mu < 47 \). The sample is small (\( n = 15 \)) and the data come from a normal population. The variance, \( \sigma^2 \), 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 \( \alpha = 0.09 \). (c) State the critical region. (d) You find that the test statistic value is \( +0.41 \). Based on your critical region, what decision do you make regarding the null hypothesis (i.e., do you Reject \( H_0 \) or Do Not Reject \( H_0 \))? (e) State your conclusion.
