Question:

Heart rate (in counts/minute) is measured every 30 minutes. The results of 20 consecutive measurements are as follows:

Heart Rate Sample Sample Heart Rate 1 68 11 79 71 12 79 3 67 13 78 4. 69 14 78 71 15 78 70 16 79 69 17 79 8. 67 18 82 70

Suppose that the standard deviation of the heart rate is Ïƒ = 3 and the target value is 70.

(a) Design a CUSUM scheme for the heart rate process. Does the process appear to be in control at the target?

(b) How many samples on average would be required to detect a shift of the mean heart rate to 80?
