A mayor running for re-election claims that during his term, average municipal taxes have fallen by $100. A conscientious statistician wants to test this claim. He surveys 38 of his neighbors and finds that their taxes decreased (in dollars) as follows:

113, 85, 109, 97, 117, 87, 105, 116, 84, 122, 118, 107, 108, 115, 100, 100, 107, 111, 101, 108, 71, 107, 80, 103, 86, 121, 117, 83, 113, 107, 124, 102, 78, 112, 96, 97, 88, 117

The statistician assumes a population standard deviation of $14. 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 ___ with distribution mean ____ and distribution standard deviation ______.

Step 3: Assuming the Claim is True, Find the Probability of Obtaining the Point Estimate.

P(___ ___ ___ ) = P(___ ___ _____ )= _____
