In a hypothesis test for the population variance, the alternate hypothesis is the population variance does not equal 17.0 . The significance level to be used is 0.05 and the sample size to be taken is 25 . The table value(s) to use from the chi-square distribution is (are):
 a. 39.364.
  b. 40.647.
  c. 12.401 and 39.364.
  d. 13.120 and 40.647.
  e. 12.401.
