Total plasma volume is important in determining the required plasma component in blood replacement therapy for a personundergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a randomsample of 48 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasmaper kilogram body weight). Assume that σ = 8.00 ml/kg for the distribution of blood plasma.When finding an 99% confidence interval, what is the critical value for confidence level? (Give your answer to two decimal places.)Z=0.005(a) Find a 99% confidence interval for the population mean blood plasma volume in male firefighters.

There is very strong evidence that the population slope differs from zero, and thus is an effective model for predicting this response variable. There is not enough evidence that the population slope differs from zero, and thus is not an effective model for predicting this response variable. Save for Later Attempts: 0 of 1 used Submit Answer
