Amagazine provided results from a poll of 500500 adults who were asked to identify their favorite pie. among the 500500 respondents, 1212% chose chocolate pie, and the margin of error was given as plus or minus±33 percentage points. given specific sample data, which confidence interval is wider: the 9595% confidence interval or the 8080% confidence interval? why is it wider? choose the correct answer below. a. anan 8080% confidence interval must be wider than a 9595% confidence interval because it contains 100%minus−8080%equals=2020% of the true population parameters, while the 9595% confidence interval only contains 100%minus−9595%equals=55% of the true population parameters. b. a 9595% confidence interval must be wider than anan 8080% confidence interval because it contains 9595% of the true population parameters, while the 8080% confidence interval only contains 8080% of the true population parameters. c. a 9595% confidence interval must be wider than anan 8080% confidence interval in order to be more confident that it captures the true value of the population proportion.

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
