Professor at the UWIOC has recently surveyed a random sample of n = 500 students. He would now like to determine whether or not the mean age of his students is over 35. If he wants to test at the 1% level of significance what rejection region should he use? a. Reject H0 if z < −2.58 b. Reject H0 if z < −2.33 c. Reject H0 if z > 2.58 d. Reject H0 if z > 2.33
