A sample mean, sample size, and population standard deviation are given. Use the one-mean z-test to perform the required hypothesis test at the given significance level. Use the critical -value approach.

= 25, n = 40, σ = 1.5, H0: μ = 22; Ha: μ ≠ 22, α = 0.05
◦ z = 12.65; critical values = ±1.96; do not reject H0
◦ z = 12.65; critical values = ±1.96; reject H0
◦ z = 12.65; critical values = ±1.645; do not reject H0
◦ z = 12.65; critical values = ±1.645; reject H0
