One factor in rating a National Hockey League team is the mean weight of its players. A random sample of players from the Detroit Red Wings was obtained. The weight (in pounds) of each player was carefully measured, and the resulting data have a sample size of 15 with a sample mean of 209 pounds and a sample standard deviation of 11.1 pounds. Assume that the distribution of the weights is normal.

a. Find the 95.5% confidence interval for the true mean weight of the players from the Detroit Red Wings

b. Interpret your answer from the interval above (part a)

c. Calculate the 95.5% lower bound of the true mean weight of the players for the Detroit Red Wings

d. Interpret your answer from the interval above (part b)

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 43 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 7.70 ml/kg for the distribution of blood plasma. (b) What conditions...
