The exchange commission recently reported that the average age of a female shareholder is 44. 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 sample data from Vancouver differ significantly enough from the exchange commission claim. Use a=0.05 if in fact true age of shareholders is 45 not 44 then what is the brokers probability of committing a type II error l: please find: null Ho null Ha graph tail right left or 2 tailed distribution (Z, t, X^2, or F) left and right critical value: calculated value : conclusion: probability of making type II error:
