3. A study is performed to investigate the heart rates measured before and after a mild 10-minute workout in a fitness session. A random of 34 members were selected and the increment in each person's heart rate (measured in beats per minute) is represented by the following data: 45 61 50 69 53 52 52 61 59 57 52 44 54 59 42 48 62 60 36 57 54 62 32 44 70 50 47 41 54 59 37 51 42 41 a) Measure the point estimate of the corresponding population mean. b) Produce a 98% confidence interval for the average increment in a person's heart rate after a mild 10-minute workout.
