Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. 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 = 15.03 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.
