If we assume that the completion times are normally distributed, find a 95% confidence interval for the true mean completion time for this task. Then find the
lower limit and upper limit of the 95% confidence interval.
Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)
