Passage
A company has provided insurance policies to several people whose age is normal with variance 36. An insurance agent of the company has claimed that the average age of policyholders who are insured through her is 30 years. We suspect that this is too low. To test the agent's claim, we have selected a random sample of 100 policyholders who purchased their policies through her. If the average age of selected 100 policyholders is greater than 31.1 years, we reject the claim; otherwise, we accept it. Based on the above data, answer the given subquestions.
Define null hypothesis and alternative hypothesis.
