Extracted text: 4. A question of interest is whether increasing the amount of exercise will decrease blood glucose ohe levels for pre-diabetic adults and if so, in what fashion. A random sample of twenty pre-diabetic oadults was obtained. The data below gives the amount of time spent exercising per week (in hours) and the person's blood glucose level (measured in mg/dL). Exercise Time Glucose Levels Exercise Time Glucose Level 1.67 155 4.5 105 2 150 3.75 125 1.5 156 95 2.3 149 6 SI 98 2.92 80 151 100 3.5 129 4 118 2.08 145 5.5 114 2.5 135 6.5 98 1.25 154 4.5 107 3.75O 127 7.5 80


Extracted text: 3. Consider once again the data describing the relationship between exercise and glucose levels described in problem 4. Use the data in problem 4 to answer the following questions. a. Find and interpret a 99% confidence interval for the population slope. b. Find and interpret a 99% confidence interval for the average blood glucose level for adults that exercise an hour a day, three days a week. c. Find and interpret a 99% prediction interval for an adult that exercises an hour a day, three days a week. d. Explicitly explain the difference between the CI found in part b and the PI found in part c. dotormine which one is the CI and which one is the PI. Note that
