A random sample of 16 subjects was asked to perform a given task. The time in seconds it took each of them to complete the task is recorded below. 48, 49, 25, 40, 40, 49, 26, 33, 26, 37, 36, 32, 35, 36, 25, 32 (Send data to calculator) (Send data to Excel) If we assume that the completion times are normally distributed, find a 95% condence interval for the true mean completion time for this task. Then find the lower limit and upper limit of the 95% confidence interval
