QUESTION 14 Fatema computed a 95% confidence interval for the average time (in minutes) spent on social networking daily by college students in UAE as (107.12, 112.88). Which of the following would be a 90% confidence interval calculated from the same set of sample data that Fatema used to construct the 95% confidence interval above? (106.81, 113.19) (107.58, 112.42) (106.21, 113.79) (104.66, 114.34) QUESTION 15 Which of the following is the widest confidence interval? A 95% confidence interval with n=50. A 97% confidence interval with n=50. A 97% confidence interval with n=100. A 95% confidence interval with n=100. QUESTION 16 It is highly recommended that adults should monitor a specific health indicator, for example weight, diet, or exercise. Suppose a random sample of 426 ZU students is obtained, and all were asked if they monitor their health in some way. If 109 of them indicated that they do, find the upper confidence limit (UCL) of the 92% confidence interval for the proportion of ZU students who monitor their health in some way. Round your answer to two decimal places.
