A newsgroup is interested in constructing a 95% confidence interval for the difference in the proportions ofTexans and New Yorkers who favor a new Green initiative. Of the 528 randomly selected Texans surveyed, 432were in favor of the initiative and of the 554 randomly selected New Yorkers surveyed, 455 were in favor ofthe initiative.a. With 95% 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 528 randomly selected Texans and 554 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.Ouestion Help: M Message instructor

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]
