Problem 8.24 In order to test H0 : µ ≤ 35 against H1 : µ > 35 a researcher records the observed value x of the sample mean of a random sample of size n = 9 taken from a normal distribution N(µ, 49). Compute the P-value of the test if the observed value x is:

(a) x = 36.

(b) x = 37.

(c) x = 39.

(d) For which of the computed P-values in parts (a), (b), and (c), would the null hypothesis be rejected at the 5% level of significance?
