Five 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 obtained 122 114 97 101 90 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 with no outliers Round the lower and upper bounds to one decimal place CLEE OA Lower bound 92 4 Upper bound 117 2 We are 95 confident that the mean pulse rate of men after 6 minutes of exercise is between 92 4 and 117 2 beats per minute O B Lower bound 86 8 Upper bound 122 8 The mean pulse rate for 95 of all men after 6 minutes of exercise is between 86 8 and 122 8 beats per minute OC Lower bound 93 4 Upper bound 116 2 We are 95 confident that the mean pulse rate of men after 6 minutes of exercise is between 93 4 and 116 2 beats per minute O D Lower bound 88 7 Upper bound 120 9 We are 95 confident that the mean pulse rate of men after 6 minutes of exercise is between 88 7 and 120 9 beats per minute
