A split ticket is a voting pattern in which a voter casts votes for candidates from more than one political party. In a recent study, 1,000 men and women were asked whether they voted a split ticket in the last election. The totals are shown in the following table. Yes, split ticket No, did not split ticket Total Men a с 800 Women b d 200 Total 600 400 1,000 What value of a would indicate no association between gender and voting pattern for the people in the sample?

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.

just the last part, thank you!
A study was conducted of pleas made by 1,025 criminals. Among those criminals, 953 pled guilty, and 395 of them were sentenced to prison. Among the 72 other criminals, who pled not guilty, 59 were sent to prison. Complete (a) through (d). a. What percentage of the criminals pled guilty? % (Round to the nearest tenth as needed.) b. What percentage of the criminals were sent to prison? % (Round to the nearest tenth as needed.) c. Among those who pled guilty, what is the percentage who were sent to prison? % (Round to the nearest tenth as needed.) d. Among those who pled not guilty, what is the percentage who were sent to prison? % (Round to the nearest tenth as needed.) ←
This review problem has me stuck. I know I'm doing a "paired differences" test but I'm not completely sure what that implies. I feel like it's some sort of hypothesis test, but it's not something I remember covering in class. A bit of assistance would be fantastic!
Among US Households, only 15% have a landline phone. A telemarketing campaign will involve a SRS of 2250 households. Let X be the number of households that have a landline phone among the 2250 households randomly chosen. What is the mean of X? Do Not Round.
You are testing the claim that the proportion of men who own cats is smaller than the proportion of women who own cats.You sample 110 men, and 90% own cats.You sample 90 women, and 20% own cats.Find the proportion of the pooled samples, (pcpc), as a decimal, rounded to two decimal places.
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.

A programmer plans to develop a new software system. In planning for the operating system that he will use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 99% confident that his estimate is in error by no more than two percentage points question mark Complete parts (a) a) Assume that nothing is known about the percentage of computers with new operating systems.
