A newsgroup is interested in constructing a 99% confidence interval for the difference in the proportions ofTexans and New Yorkers who favor a new Green initiative. Of the 600 randomly selected Texans surveyed,407 were in favor of the initiative and of the 538 randomly selected New Yorkers surveyed, 467 were infavor of the initiative.a. With 99% confidence the difference in the proportions of Texans and New Yorkers who favor a newGreen initiative is between(round to 3 decimal places) and(round to 3 decimal places).b. If many groups of 600 randomly selected Texans and 538 randomly selected New Yorkers were surveyed,then a different confidence interval would be produced from each group. Aboutpercent of theseconfidence intervals will contain the true population proportion of the difference in the proportions ofTexans and New Yorkers who favor a new Green initiative and aboutpercent will not contain thetrue population difference in proportions.

A student polls his school to see if students in the school district are for or against the new legislation regarding school uniforms. She surveys 600 students and finds that 480 are against the new legislation. Compute a 95% confidence interval for the true percent of students who are against the new legislation, and interpret the confidence interval.
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
A national polling organization conducted a survey asking people whether they would consider buying an electric car if petrol prices continue to rise. In the low-income sample of 200 people asked, 175 said they would not buy an electric car no matter how high petrol prices rise. In the high-income sample of 200 people asked, 127 responded the same. The 95% confidence interval for the difference in proportion of low income people and high income people who would never consider buying an electric car no matter how high the price of petrol got (rounded off to three decimals) is: A. [0.173 : 0.307] B. [0.145 : 0.335] C. [0.159 : 0.321] D. [0.172 : 0.308]

Debbie and Ethan are going to construct confidence intervals from the same simple random sample. Debbie's confidence interval will have a 98% confidence interval and Ethan's will have a 95% confidence interval. A. Which confidence interval, if there is a difference will have a larger margin of error? B. Which confidence interval is more likely to cover the population mean, if there is a difference I am using a Ti84 and need to know how to get the answer.
