[cherise1989]

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.

Question 2

In testing a population variance or constructing a confidence interval for the population variance, an essential assumption is that:
 a. sample size exceeds 30.
  b. expected frequencies equal or exceed 5.
  c. the population is uniformly distributed.
