stal 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 dividual 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 a 7 80 ml kg for e distribution of blood plasma a Find a 99 confidence interval for the population mean blood plasma volume in male 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 On is large the distribution of volumes is uniform o is known Oo is unknown the distribution of volumes is normal c Interpret your results in the context of this problem O The probability that this interval contains the true average blood plasma volume in male firefighters is 0 01 O We are 99 confident that the true average blood plasma volume in male firefighters falls within this interval We are 1 confident that the true average blood plasma volume in male firefighters falls within this interval The probability that this interval contains the true average blood plasma volume in male firefighters is 0 99 d Find the sample size necessary for a 99 confidence level with maximal margin of error E 2 70 for the mean plasma yolume in male firefighters
