The weekly expenditure on groceries of a random sample of 100 family households was recorded. It was estimated that the mean expenditure was approximately $240. With rising interest rates and petrol prices, it was anticipated that grocery expenditure might decrease. Which hypothesis test would you use to test this claim? a) One tailed, one sample t-test b) Two tailed, one sample t-test c) One tailed, z-test d) One-tailed Paired Samples t-test e) Chi Square
B. Determine the test statistic. ____ C. Do the results support the theory that because the kicks are so fast, goalkeepers have no time to react, so the directions of their jumps are independent of the directions of the kicks? There is (insufficient/sufficient) evidence to warrant rejection of the claim that the direction of the kick is independent of the direction of the goalkeeper jump. The results (support/ do not support) the theory that because the kicks are so fast, goalkeepers have no time to react.

.A tourist wants to make a trip to a small city and visit the crowded shopping center. The city's mayor claims less that 10% of its residents are non- vaccinated against a very serious infectious disease. He is deciding whether to make a trip to the city's shopping center, so performs a hypothesis test to determine whether the city's mayor claim is true. 1. Let represent the proportion of the residents who are non-vaccinated, write the null and alternative hypothesis. 2. When will type 1 error occur in this situation? 3. When will type Il error occur in this situation? 4. Which error is more serious and risky in this situation? EXPLAIN
