A study оf the аbility оf individuаls tо wаlk in a straight line reported the accompanying data oncadence (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 ofcadence is approximately normal. A descriptive summary of the data from MINITAB follows. Variable N Mean Median StDev Cadence 20 0.9255 0.9300 0.0809 a. Calculate and interpret a 99% confidence interval for a population mean cadence.In calculating the CI, did you use critical t score or critical z score? (type t or z) Use critical [score] score (t or z). 99% confidence interval is ([LL], [UL]) (round to 3 decimals)
