A random sample is obtained from a population with

variance o? = 625, and the sample mean is computed.

Test the null hypothesis Haid = 100 versus the alternative hypothesis H: > 100 with a = 0.05. Compute the critical value X, and state your decision rule

for the following options.

a. Sample size - 25

b. Sample size n = 16

c. Sample size = 44

d. Sample size n = 32
