A mayor running for re-election claims that during his term, average municipal taxes have fallen by $150. A conscientious statistician wants to test this claim. She surveys 42 of her neighbors and finds that their taxes decreased (in dollars) as follows: 137, 211, 147, 146, 113, 126, 165, 165, 191, 133, 156, 181, 160, 213, 158, 159, 251, 202, 176, 239, 134, 126, 156, 128, 165, 150, 123, 192, 134, 166, 225, 153, 121, 150, 163, 228, 209, 109, 191, 165, 202, 157 The statistician assumes a population standard deviation of $35.
