A normal resting heart rate for adults ranges from about 60 to 100 beats per minute BPM A doctor would like to estimate the average heart rate for one of her patients The doctor instructs her patient to measure their resting heart rate twice a day for one week The measurements are listed below Assume that the distribution of all heart rate measurements of this patient is approximately normally distributed X 89 07 8 4 141 92 81 95 2232 A 95 confidence interval is given by 94 91 89 89 Determine the point estimate and the sample standard deviation s Round the solutions to four decimal places if necessary 88 88 88 93 90 88 81 Using a 95 confidence level determine the margin of error E and a confidence interval for the average resting heart rate of this patient Report the confidence interval using interval notation Round solutions to two decimal places if necessary The margin of error is given by E
