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 599 randomly selected Texans surveyed, 370were in favor of the initiative and of the 545 randomly selected New Yorkers surveyed, 474 were in favor ofthe initiative.a. With 99% confidence the difference in the proportions of Texans and New Yorkers who favor a new Greeninitiative is between (round to 3 decimal places) and (round to 3 decimal places).b. If many groups of 599 randomly selected Texans and 545 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 of Texansand New Yorkers who favor a new Green initiative and aboutpercent will not contain the truepopulation difference in proportions.

A newsgroup is interested in constructing a 95% confidence interval for the difference in the proportions of Texans and New Yorkers who favor a new Green initiative. Of the 528 randomly selected Texans surveyed, 432 were in favor of the initiative and of the 554 randomly selected New Yorkers surveyed, 455 were in favor of the initiative. a. With 95% confidence the difference in the proportions of Texans and New Yorkers who favor a new Green initiative is between (round to 3 decimal places) and (round to 3 decimal places). b. If many groups of 528 randomly selected Texans and 554 randomly selected New Yorkers were surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of the difference in the proportions of Texans and New Yorkers who favor a new Green initiative and about percent will not contain the true population difference in proportions.

A newsgroup is interested in constructing a 90% confidence interval for the difference in the proportions of Texans and New Yorkers who favor a new Green initiative. Of the 531 randomly selected Texans surveyed, 354 were in favor of the initiative and of the 559 randomly selected New Yorkers surveyed, 460 were in favor of the initiative. a. With 90% confidence the difference in the proportions of Texans and New Yorkers who favor a new (round to 3 decimal places) and (round to 3 decimal Green initiative is between places). b. If many groups of 531 randomly selected Texans and 559 randomly selected New Yorkers were surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of the difference in the proportions of Texans and New Yorkers who favor a new Green initiative and about percent will not contain the true population difference in proportions.
A sample of 100 shoppers chosen at random from all shoppers in a given province indicated that 55% of them preferred a particular store (Shoprite).i. Find a 95% confidence interval for the proportion of all the shoppers that preferred Shoprite.ii. How large a sample of shoppers should we take in order to be 95% confident that the shoppers will buy from Shoprite?
A random sample of Roosevelt High School students was asked if they prefer taking notes on a computer or using a paper and pencil. Of the 180 students who were surveyed, 75 said they preferred using the computer. The resulting 99 percent confidence interval for the proportion of students who prefer taking notes on the computer was (0.322, 0.511). The school newspaper ran a story saying that less than half of the student body prefers taking notes on a computer. Based on the interval, is the newspaper justified in its statement? Yes. The sample proportion of students who prefer taking notes on their computer was 0.417, which is less than 0.5. Yes. Since nearly the entire confidence interval contains values less than 0.5, we can be certain that less than 50% of students prefer using a computer for notes. No. Since the interval contains values above 0.5, it is plausible that more than 50% of students prefer using a computer for notes. No. Since the interval contains values above 0.5, we…
