Transcribed Image Text:9. Consider 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 the regression line.
b. Interpret, if possible, the coefficients of the regression line.
c. If possible, estimate the average blood glucose level for an adult who exercises two hours a day,
every day of the week.
d. If possible, estimate the average blood glucose level for an adult who exercises one hour a day,
three days a week.
Transcribed Image Text:4. A question of interest is whether increasing the amount of exercise will decrease blood glucose
ph levels for pre-diabetic adults and if so, in what fashion. A random sample of twenty pre-diabetic
adults 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).
