For each of the following, state the null and alternative hypotheses, the Type I and Type II errors associated with the hypotheses, and the consequences of each error.
A. The decision to implement changes in the current math program at a junior high in Bigcity will be based on a sample of students' scores on a standardized math exam. If the average is less than the statewide average of 89, all math teachers will have to participate in a workshop to revise the curriculum.
B. Expensive Clothing, Inc. thinks it had a good year and wants to reward its customers. In a typical year, sales are $75 per customer. If a random sample of this year's sales indicate a better than average year (average sales per customer are higher than $75), a $10 coupon will be given out for two weeks to each customer who spends at least $75.
C. Too Many Pets, a pet store, is concerned about its dogs. The store has enough supplies on hand to maintain an estimated in-store average of 10 dogs a day. The store wants to know whether its average dog population is actually 10 a day or some other number. If their original estimate is incorrect the store will have to invest in research to determine the actual average and decide how to accommodate the change.
