1. A report states the average temperature for the month of June on a specific tropical island is 97 degrees F. A meteorologist claims the report is not correct.. Data collected from 38 areas on the island showed an average temperature of 93 degrees F. The population  standard deviation is known to be 8.0 degrees F.  At alpha = 0.01, can the report's average be rejected? For multiple choice question #1, tell what type of test: right-tailed, left-tailed, or two-tailed.

For question #2, identify the alternative hypothesis (H1) from choices given.

For question #3 give just your calculated z-value that you are going to use to make a decision on the null hypothesis.

For question #4, answer True or False as to whether the null hypothesis is rejected.
