We wish to test the hypotheses HO: µ 80 versus H1: H 780 at a 14% level of significance. Here u denotes the average score X on a standardized test for students who have taken a preparation course for the exam.

A random sample of 76 eighth grade students' scores on a national mathematics assessment test has a mean score of 283. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 280. Assume that the population standard deviation is 31. At α=0.04, is there enough evidence to support the administrator's claim? Complete parts (a) through (e).

The vaccine Y recipients had a mean 6AEQ of y = 148. It is recognized that the true standard deviation of 6AEQ for vaccine X recipients is o, = 9.7 while it is recognized that the true standard deviation of 6AEQ for vaccine Y recipients is o, = 10.5.

According to a report done by S & J Power, the mean lifetime of the light bulbs it manufactures is 49 months. A researcher for a consumer advocate group tests this by selecting 50 bulbs at random. For the bulbs in the sample, the mean lifetime is 50 months. It is known that the population standard deviation of the lifetimes is 8 months. Can we conclude, at the 0.01 level of significance, that the population mean lifetime, µ, of light bulbs made by this manufacturer differs from 49 months? Perform a two-tailed test.
