Construct a 95% Z-interval or a 95% t-interval about the population mean. Assume the data come from a population that is approximately normal v Fifteen randomly selected men were asked to run on a treadmill for 6 minutes. After the 6 minutes, their pulses were measured and the following data were o 105 94 98 88 104 101 99 85 84 124 122 114 97 101 90 O (93.7, 107.1); we are 95% confident that the mean pulse rate of men after 6 minutes of exercise is between 93.7 and 107.1 beats per minute. O (94.9, 105.9); we are 95% confident that the mean pulse rate of men after 6 minutes of exercise is between 94.9 and 105.9 beats per minute. O (95.2, 105.6); we are 95% confident that the mean pulse rate of men after 6 minutes of exercise is between 95.2 and 105.6 beats per minute. O (94.2, 106.6); we are 959% confident that the mean pulse rate of men after 6 minutes of exercise is between 94.2 and 106.6 beats per minute.
