A sample of 15 female collegiate golfers was selected and the clubhead velocity (km/h) while swinging a driver was determined for each one, resulting in the following data ("Hip Rotational Velocities during the Full Golf Swing," J. of Sports Science and Medicine, 2009: 296–299):   .6944 .7500 .8056 .8611 .9167 .9722 69.0 69.7 72.7 80.3 81.0
The corresponding z percentiles are:.
  85.0 86.0 86.3 86.7 87.7 91.
89.3 90.7 91.0 92.5 93.0
Does it appear plausible that propagation life has a normal distribution? Explain.
