Oswald is registering for classes next semester. He uses the Quantitative Reasoning Process to decide between two teachers, Dr. Adams, and Dr. Baldwin . He speaks to 17 friends that previously took the course from Dr. Adams and also speaks to17 friends that took it from Dr. Baldwin. Eight of his friends said they highly recommend Dr. Adams. Eleven of his friends highly recommend Dr. Baldwin.

He speaks to 17 friends that previously took the course from Dr. Adams and also speaks to 17 friends that took it from Dr. Baldwin. Eight of his friends said they highly recommend Dr. Adams. Eleven of his friends highly recommend Dr. Baldwin. Based on Oswald's minimal study, what percent of students "highly recommend" Dr. Adams? % (Round the final percentage to one decimal place} What percent "highly recommend" Dr.Elaldwin'? % (Round the final percentage to one decimal place} To be statistically accurate in his decision, Oswald decides to create a 95% condence interval for his tvvo percentages. What values does he find for each confidence interval? Confidence interval for the true proportion that "highly recommend" Dr Adams: (Enter the low value in the first blank and the high value in the second blank. Bound values to one decimal place) Number %, Number % Confidence interval for the true proportion that "highly recommend" Dr. Baldwin: (Enter the low value in the first blank and the high value in the second blank. Bound values to one decimal place) Number %, Number % Do Oswald's confidence intervals Show evidence that a greater percentage of students favor one teacher over the other? 0 Yes, the confidence intervals overlap, so clearly one teacher is preferred by students over the other teacher. 0 Yes, the confidence intervals do not overlap, so clearly one teacher is preferred by students over the other teacher. No, the confidence intervals overlap, so the percentages of students that approve of each teacher are really the same as far as we can tell. 0 No, the confidence intervals do not overlap, so the percentages of students that approve of each teacher are really the same as far as we can tell. The table below shows which hand is favored by each person from a sample of 100 people (50 male and 50 female). Use the information in the table to answer the following questions. ' Ight-Handed Determine the probability that a randomly selected person from the sample will be female or left-handed. m % (Bound to the nearest whole percentage} Compute a 95% confidence interval for the true proportion of the population that is left-handed. Compute a 95% confidence interval for the true proportion of the population that is right-handed
