Question
A mayor running for re-election claims that during his term, average municipal taxes have fallen by $125. A
conscientious statistician wants to test this claim. He surveys 37 of his neighbors and finds that their taxes
decreased (in dollars) as follows:
121, 139, 121, 125, 118, 145, 141, 91, 127, 136, 144, 154, 131, 139, 139, 125, 108, 130, 125, 106, 137, 148,
154, 134, 137, 112, 96, 114, 114, 126, 133, 129, 94, 129, 148, 163, 121
The statistician assumes a population standard deviation of $19. Do you think the statistician should reject
the 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 with
distribution mean
and distribution standard deviation
Step 3: Assuming the Claim is True, Find the Probability of Obtaining the Point Estimate.
