A study of the ability of individuals to walk in a straight line reported the accompanying data on cadence (strides per seconds) for a sample of n = 20 randomly selected healthy men: .95 .81 .93 .95 .93 .86 1.05 .92 .85 .81 .92 .96 .92 1.00 .78 1.06 1.06 .96 .85 .92 A normal probability plot gives substantial support to the assumption that the population distribution of cadence is approximately normal. Calculate and interpret 95% confidence intervals for population mean and standard deviation cadence.
