Chapter 12, Problem 1CP
In a study conducted by Zogby International for the Democrat and Chronicle, more than 700 New Yorkers were polled to determine whether the New York state government works. Respondents surveyed were asked questions involving pay cuts for state legislators, restrictions on lobbyists, term limits for legislators, and whether state citizens should be able to put matters directly on the state ballot for a vote. The results regarding several proposed reforms had broad support, crossing all demographic and political lines.
Suppose that a follow-up survey of 100 individuals who live in the western region of New York was conducted. The party affiliation (Democrat. Independent. Republican) of each individual surveyed was recorded, as well as their responses to the following three questions.
- 1. Should legislative pay be cut for every day the state budget is late?
Yes ___ No ____
- 2. Should there be more restrictions on lobbyists?
Yes ___ No ___
- 3. Should there be term limits requiring that legislators serve a fixed number of years?
Yes ___ No ___
The responses were coded using 1 for a Yes response and 2 for a no response. The complete data set is available in the file named NYReform.

Proponents claim that these laws are necessary to reduce voter fraud. Opponents claim that voter fraud is rare and that since as many as 11% of eligible voters do not have the required identification, these tougher laws will discourage millions of minorities and low-income Americans from voting. The Washington Post conducted a national poll (July 7-19, 2012) and found that 1558 out of 2064 adults supported the tougher voter ID laws. 1)Construct a 95% confidence interval for the proportion of adults who approve of tougher voter ID laws.

Yet an article published by the Detroit Free Press titled “Assistance: IRS Help Centers Give the Wrong Information” discusses the propensity of IRS staff employees to give incorrect tax information to taxpayers who call with questions. Then IRS Inspector General Pamela Gardiner told a Senate subcommittee that “the IRS employees at 400 taxpayer assistance centers nationwide encountered 8.5 million taxpayers face-to-face last year. The problem: When inspector general auditors posing as taxpayers asked them to answer tax questions, the answers were right 69% of the time.” Suppose an independent commission was formed to test whether the 0.69 accuracy rate is correct or whether it is actually higher or lower. The commission has randomly selected n = 180 tax returns that were completed by IRS assistance employees and found that 105 of the returns were…arrow_forwardA meat-processing company in the Midwest produces and markets a package of eight small sausage sandwiches.
