Calculate the critical area for alpha = 0.05 b. The measured X=10, calculate the P-value ans: [14.98, infinity) and p = 0.135 . I know that the critical area is the collection of values for which H0 is rejected in favor of H1. In the case of a normal distribution I know how to calculate the critical region.
