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. Perform the residual analysis to verify the assumptions of the model. If any assumptions are violated, clearly state which assumption(s) are violated. b. Determine if there are any outliers. If there are outliers, state which data value is an outlier.
