Question: Suppose that a random sample of nine measurements from a
Suppose that a random sample of nine measurements from a normally distributed population gives a sample mean of 2.57 and a sample standard deviation of .3. Use critical values to test H0: μ = 3 versus Ha: μ ≠ 3 using levels of significance α = .10, α = .05, α = .01, and α = .001.
