Question: An article in Quality Engineering [Designed Experiment to Stabilize Blood Glucose Levels (19992000,)] described an experiment to minimize variations in blood glucose levels. The treatment

An article in Quality Engineering [€œDesigned Experiment to Stabilize Blood Glucose Levels€ (1999€“2000,)] described an experiment to minimize variations in blood glucose levels. The treatment was the exercise time on a Nordic Track cross-country skier (10 or 20 min). The experiment was blocked for time of day. The data were as follows:

Exercise (min) Time of Day Average Blood Glucose 71.5 10 pm 10 103.0 am 20 83.5 am 20 126.0 pm 10 125.5 10 129.5 pm 20 9

(a) Is there an effect of exercise time on the average blood glucose? Use Î± = 0.05.

(b) Find the P-value for the test in part (a).

Exercise (min) Time of Day Average Blood Glucose 71.5 10 pm 10 103.0 am 20 83.5 am 20 126.0 pm 10 125.5 10 129.5 pm 20 95.0 pm 93.0 am
