A man measures his heart rate before using a treadmill and then after walking on a treadmill for 10 minutes on 7 separate days. His mean heart rate at baseline and 10 minutes after treadmill walking is 85 and 93 beats per minute (bpm), respectively. The mean change from baseline to 10 minutes is 8 bpm with a standard deviation of 6 bpm. (a) What test can we use to compare pre- and post-treadmill heart rate? (b) Implement the test in 2a, and report a two-tailed p-value. (c) Provide a 90% confidence interval (CI) for the mean change in heart rate after using the treadmill for 10 minutes. (d) What is your overall conclusion concerning the data? this is a review question of ch8 bernard rosner. the solution is not provided at bartleby for this review question
