A newsgroup is interested in constructing a 90% confidence interval for the difference in the proportions ofTexans 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 infavor 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 decimalGreen initiative is betweenplaces).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. Aboutpercent ofthese confidence intervals will contain the true population proportion of the difference in the proportionsof Texans and New Yorkers who favor a new Green initiative and aboutpercent will not containthe true population difference in proportions.
