QUESTION 5 In a recent study, 820 American adults were surveyed and 61% said they would travel less this year for nonbusiness trips than last year. Find the 95% confidence interval for the true proportion of adults who said that they would travel less this year for nonbusiness trips. O (0.528, 0.583) (0.576, 0.643) (0.843 , 0.902) O (0.523, 0.588) QUESTION 6 A survey of 302 randomly selected students at one university found that 296 students think that there is not enough parking on campus. Find margin of error for a 90% confidence interval for the proportion of all students at this university who think that there is not enough parking on campus. Round your answer to three decimal places. Type your answer below. ON 7 Out of 190 randomly selected adults in the U.S. who were surveyed, 71 excercise on a regular basis. A 95% confidence interval is found to be (0.305, 0.442) Interpret the confidence interval. We can say with 95% confidence that the proportion of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%) o We can say the proportion of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%). We can say the proportion of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%) is 95%. We can say 95% of all adults in the US who excercise on a regular basis is between 0.305 and 0.442 (or between 30.5% and 44.2%).
