Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery Pasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 40 male firefighters are tested and that they have a plasma volume sample mean of x - 17.5 mil milliers plasma per klogram body weight). Assume that . - 7.40 mkg for the distribution of blood plasma (a) Find a 99% confidence interval for the population mean blood plasma volume in mole firefighters. What is the margin of error? (Round your answers to two decimal places.) lower limit upper limit margin of error (b) What conditions are necessary for your calculations? (Select all that apply.) nis large the distribution of volumes is normal Dis unknown the distribution of volumes s uniform e is known (c) Interpret your results in the context of this problem The probability that this interval contains the true average bloed plasma volume in male firefighters is 0.99 We are 99% confident that the true average blood plasma volume in male freighter falls within this nerva. We are confident that the trut average blood plasma volume in male fighter falls within this interval The probability that this interval contains the true average blood plasma volume in male fighters is 0.01 (d) Find the sample size necessary for a 99% confidence level with maximal margin of error E - 2.20 for the mean plasma volume in male firefighters. (Round up to the nearest whole number: male firefighters
