# Question

Consider the hypothesis test where the hypotheses are Ho: µ = 26.4 and Ha: µ < 26.4 . A sample of size 64 is randomly selected and yields a sample mean of 23.6.

a. If it is known that s = 12 , how many standard errors below µ = 26.4 is the sample mean, = 23.6 ?

b. If , would you reject Ho? Explain.
