Calculate the p-value for the following conditions and determine whether to reject the null hypothesis:

a. one-tail (lower) test, zp = -1.36, and a = 0.05

b. one-tail (upper) test, zp = 1.28, and a = 0.10

c. two-tail test, zp = 2.29, and a = 0.05

d. two-tail test, zp = -0.90, and a = 0.01 AppendixLO1
