n a poll of 150 randomly selected U.S. adults, 76 said they favored a new proposition. Based on this poll, compute a 95% confidence interval for the proportion of all U.S. adults in favor of the proposition (at the time of the poll). Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) Lower limit: Upper limit:

A researcher wants to estimate the actual proportion of citizens of a certain country who feel that the president does an acceptable job after 30 months in office. His estimate will be with a 99% confidence interval. How many individuals must the researcher interview if he wants his estimate to be within 2%? Write your answer without using commas.

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.

Out of 500 people sampled, 145 received flu vaccinations this year. Based on this, construct a 90% confidence interval for the true population proportion of people who received flu vaccinations this year.Give your answers as decimals, to three places

In a survey of 2319 ​adults, 704 say they believe in UFOs.   Construct a 90% confidence interval for the population proportion of adults who believe in UFOs. A 90​% confidence interval for the population proportion is ​(.  ,  ). ​(Round to three decimal places as​ needed.)

Tonya wants to estimate what proportion of her school's seniors plan to attend the prom. She interviews an SRS of 50 of the 750 seniors in her school and finds that 36 plan to go to the prom. Tonya then calculates a 90% confidence interval of (0.616, 0.824). Interpret Tonya's interval in context. 90% of the seniors at Tonya's high school are between 61.6% and 82.4% likely to attend prom. We can be 90% confident that the sample proportion is captured by the confidence interval. We are 90% confident that the interval from 0.616 to 0.824 captures the true proportion of all seniors at Tonya's high school who plan to attend the prom. O If Tonya took many samples, 90% of them would find that 72.4% of the seniors in the sample plan on attending prom. The percent of seniors at Tonya's high school who plan to attend the prom is certain to be between 61.6% and 82.4%. terms of use contact us help careers privacy policy about us

b. In the year 2000, a survey of 1171 U.S. adults were asked who they felt was the greatest President. Of those surveyed, 397 reported that Abraham Lincoln was the greatest President. Use this data to construct a 99% confidence interval for the population proportion of all U.S. adults who would say that Abraham Lincoln was the greatest president before the year 2000. Answer using decimals and round to four decimal places
