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 = Determine the point estimate, and the sample standard deviation, s. Round the solutions to four decimal places, if necessary. S = A 95% confidence interval is given by 93 87 81 85 91 86 84 85 80 93 87 85 80 88 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 = Hola Video 1 Video 2
