An Article in the Journal of Sports Science (1987, Vol. 5, pp. 261-271) presents the results of an investigation of the hemoglobin level of Canadian Olympic ice hockey players. A random sample of 20 players is selected and the hemoglobin level is measured. The resulting sample mean and standard deviation(g/dl) are x= 15.47 and s = 0.6155 Use this information to calculate a 95% two-sided confidence interval on the mean hemoglobin level and a 95% two-sided confidence interval on the variance. Assume the data are normally distributed. Round your answers to 2 decimal places.

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...

An article in Knee Surgery, Sports Traumatology, Arthroscopy (2005, Vol. 13, pp. 273–279) “Arthroscopic meniscal repair with an absorbable screw: results and surgical technique” showed that only 25 out of 37 tears (67.6%) located between 3 and 6 mm from the meniscus rim were healed. (a) Calculate a 99% two-sided confidence interval on the proportion of such tears that will heal. Round the answers to 3 decimal places. (b) Calculate a 99% lower confidence bound on the proportion of such...

An article in the Journal of Aircraft (1986, Vol. 23, pp. 859-864) described a new equivalent plate analysis method formulation that is capable of modeling aircraft structures such as cranked wing boxes and that produces results similar to the more computationally intensive finite element analysis method. Natural vibration frequencies for the cranked wing box structure are calculated using both methods, and results for the first seven natural frequencies are the following: Finite 14.58 48.52 97.22 113.99 174.73 212.72 277.38 and...
