Construct a 95% Z-interval or a 95% t-interval about the population mean. Add the data below into a spreadsheet on the TI-Nspire if you need to calculate the mean. Assume the data come from a population that is approximately normal with no outliers.
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 obtained:
105 94 98 88 104
101 99 85 84 124
122 114 97 101 90
a.
(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.
b.
(94.2, 106.6); we are 95% confident that the mean pulse rate of men after 6 minutes of exercise is between 94.2 and 106.6 beats per minute.
c.
(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.
d.
(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
