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 99% confidence interval of the standard deviation of the skating performance test. Assume population is approximately normally distributed. Round your answers to 3 decimal places. i sos i

Expert Solution
Step 1: Determine given information

The sample size, i.e., the sampled number of hockey players, n=17.

The sample standard deviation of the performance (in seconds), σ=0.09.

The desired confidence level is 99%.
