A question of interest is whether increasing the amot 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).

4. A question of interest is whether increasing the amount of exercise will decrease blood glucose 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).
