Question #2020052: Confidence Intervals


Question: Can We Really Walk Straight?

A study of the ability of individuals to walk in a straight line reported the accompanying data on cadence (strides per second) for a sample of n = 20 randomly selected healthy men:

.95 .85 .92 .95 .93

.86 1.00 .92 .85 .81

.78 .93 .93 1.05 .93

1.06 1.06 .96 .81 .96

A normal probability plot gives substantial support to the assumption that the population distribution of cadence is normal. Calculate and interpret 95% confidence intervals for population mean and standard deviation cadence.
