A newsgroup is interested in constructing a 99% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 567 randomly selected Americans surveyed, 353 were in favor of the initiative. a.  With 99% confidence the proportion of all Americans who favor the new Green initiative is between and . b.  If many groups of 567 randomly selected Americans 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 Americans who favor the Green initiative and about percent will not contain the true population proportion.

The second annual Airplane Etiquette Study commissioned by Expedia asked 1000 Americans to rank the most annoying on-board behaviors of fellow passengers. Rear seat kickers topped the list with 67% of those surveyed ranking this annoying behavior as number one. You create a 99% confidence interval and find the population proportion to be within 0.038 of 0.67, or between (0.632, 0.708). Which of the following statements gives a valid interpretation of this interval? There is a 67% chance that between 63.2% and 70.8% of all Americans would rank rear seat kickers as the most annoying on-board behavior of fellow passengers. There is a 99% chance that between 63.2% and 70.8% of all Americans would rank rear seat kickers as the most annoying on-board behavior of fellow passengers. You are 99% confident that between 63.2% and 70.8% of the 1000 sampled passengers ranked rear seat kickers as the most annoying on-board behavior of fellow passengers. You are 99% confident that between 63.2% and…

A survey asked, "How many tattoos do you currently have on your body?" Of the 1217 males surveyed, 179 responded that they had at least one tattoo. Of the 1075 females surveyed, 137 responded that they had at least one tattoo. Construct a 90% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. ... Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 90% confidence interval for p₁-P2- The lower bound is The upper bound is (Round to three decimal places as needed.) Interpret the interval. OA. There is 90% confidence that the difference of the proportions is in the interval. Conclude that there is a significant difference in the proportion of males and females that have at least one tattoo. OB. There is a 90% probability that the difference of the proportions is in the interval.…

CNN is conducting a poll, and wants to produce a 90% confidence interval for the proportion of all New York residents who favor legalizing recreational marijuana. Of the 602 randomly selected New Yorkers surveyed, 394 were in favor of the initiative. a.   With 90% confidence, the proportion of New York residents who favor legalizing recreational marijuana is between  BLANK and BLANK.  b.   Suppose that we survey 602 randomly selected Americans many times, and calculate a confidence interval for each group. About Blank . percent of these confidence intervals will contain the true population proportion of New Yorkers who favor legalizing recreational marijuana, and about BLANK   percent will not contain the true population proportion.
