A mayor running for re-election claims that during his term, average municipal taxes have fallen by $275. A conscientious statistician wants to test this claim. She surveys 41 of her neighbors and finds that their taxes decreased (in dollars) as follows: 291, 304, 368, 379, 284, 248, 225, 338, 207, 312, 202, 241, 176, 249, 290, 244, 299, 275, 230, 333, 263, 253, 236, 318, 282, 230, 300, 293, 259, 288, 295, 269, 314, 279, 261, 326, 305, 304, 286, 239, 314 The statistician assumes a population standard deviation of $50. Do you think the statistician should reject the mayor's claim? Why or why not? Step 1: State the hypothesis. 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
