1.) I want to estimate the proportion of adults who like sci-fi movies. How many people should I poll to be 96% confident that I am within 1% of the population proportion? 2.) A survey of 200 college students revealed that 160 of them eat dessert daily. Construct a 95% confidence interval for the population proportion of college students who eat dessert daily. Can we claim that 75% eart dessert daily? 3.) I want to estimate the mean number of minutes that a 7-year-old watches TV daily. How many kids should I poll in order to be 99% confident that I am within 15 minutes of the actual time? Assume o = 45 min. 4.) The following are wait times (in minutes) at a certain DMV: 25 76 56 45 35 88 75 66 45 77 65 66 43 65 a.) Construct a 95% confidence interval for the mean wait time at this DMV. Is it reasonable to say that the wait time is 30 min? b.) Construct a 90% confidence interval for the standard deviation of wait times 5.) Use the information in #2. At a = 0.05, test the claim that 75% of college students eat dessert daily. 6.) Use the information in #4. At a = 0.05, test the claim that the mean wait time at the DMV is above 30 min. 7.) Use the information in #4. At a = 0.01, test the claim that the standard deviation is 10
