# Hypothesis testing - Finding critical values and P-values

1. In the following test, the variance is known. What is the rejection rule for the null hypothesis, if the level of significance is 0.06?

H_o : Mu ,< equal to, Mu_o

H_a : Mu > Mu_o

Note: Your answer should be a sentence and include some specific value(s).

2. In the following test, the variance is unknown and the sample size is 25. What is the rejection rule if the level of significance is 0.01?

H_o : Mu > equal to Mu_o

H_a : Mu < Mu_o
