A researcher is gathering data to design a wearable device that measures heart rate from the wrist. He/She took wrist measuremen
ts from 10 people to determine what the average wrist size should be for said wearable device. The mean and standard deviation of 10 wrist measurements were calculated to be: Mean, (inches) i = 7.838 Standard | Deviation, Sx Sx = 0.844 Number of samples (n) 10 Determine a 99% confidence interval for the mean presented above.
