An article in Medicine and Science in Sports and Exercise "Electrostimulation Training Effects on the Physical Performance of Ice Hockey Players," (2005, Vol. 37, pp. 455- 460) considered the use of electromyostimulation (EMS) as a method to train healthy skeletal muscle. EMS sessions consisted of 30 contractions (four-second duration, 85 Hz) and were carried out three times per week for three weeks on 17 ice hockey players. The ten- meter skating performance test showed a standard deviation of 0.09 seconds. Construct a 95% confidence interval of the standard deviation of the skating performance test Assume population is

and Exercise "Electrostimulation Training
Effects on the Physical Performance of Ice
Hockey Players," (2005, Vol. 37, pp. 455-
460) considered the use of
electromyostimulation (EMS) as a method
to train healthy skeletal muscle. EMS
sessions consisted of 30 contractions
(four-second duration, 85 Hz) and were
carried out three times per week for three
weeks on 17 ice hockey players. The ten-
meter skating performance test showed a
standard deviation of 0.09 seconds.
Construct a 95% confidence interval of
the standard deviation of the skating
performance test. Assume population is
approximately normally distributed.
