Test the null hypothesis Ho: u= 100 versus th alternative hypothesis H,: u> 100 with a= 0.05. Compute the critical value x, and state your decision rule for the options below. a. The population variance is o2 = 225. b. The population variance is o2 = 400. c. The population variance is o2 = 625. .2. d. The population variance is o? = 600. a.
