A mayor running for re-election claims that during his term, average municipal taxes have fallen by $225. A conscientious statistician wants to test this claim. She surveys 37 of her neighbors and finds that their taxe decreased (in dollars) as follows: 239, 231, 221, 213, 237, 213, 225, 240, 238, 217, 226, 221, 189, 189, 222, 219, 219, 226, 209, 225, 243, 223, 248, 258, 221, 234, 267, 225, 225, 217, 215, 236, 245, 241, 256, 226, 220 The statistician assumes a population standard deviation of $14. Do you think the statistician should reject che mayor's claim? Why or why not? Step 1: State the hypothesis. ? v = Step 2: Determine the Features of the Distribution of Point Estimates Using the Central Limit Theorem By the Central Limit Theorem, we know that the point estimates are Select an answer v with distribution mean and distribution standard deviation Step 3: Assuming the Claim is True, Find the Probability of Obtaining the Point Estimate. P( ? ♥ | ? v = P(|? ♥||? ♥ Step 4: Make a Conclusion About the Claim. What do you think? Based on the probability you calculated in step 3 of obtaining the point estimate, woule you reject the claim? Think about your answer to this step yourself; this step is not graded.
