I'm not sure how to solve this

The Exchange Commission recently reported that the average age of a female shareholder is 44 years. A broker in Vancouver wants to know whether this figure applies to the female shareholders in Vancouver. The broker secures a master list of shareholders in Vancouver and takes a random sample of 58 women. Suppose the average age for shareholders in the sample is 45.1 years, with a population standard deviation of 8.7 years. Test to determine whether the broker's sample data from Vancouver differ significantly enough from the Exchange Commission's claim. Use a . 0.05. If in fact the true age of shareholders is 45 not 44 then what is the broker's probability of committing a Type II error: Test Statistic Formula #: Hypothesis Population: OOne OTWO OMultiple Null Ho : Alternate HA: Graph: Distribution: Decision Criteria (If applicable) Left Critical Value: (if applicable) Right Critical value: Calculated Value Conclusion-1 Conclusion-2 There Is evidence to state that female shareholders in Vancouver differ from Exchange claim Type-2 Error Probability of making type-2 error is
