Question

1. 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 50 male firefighters are tested and that they have a plasma volume sample mean of x-37.5 m1kg . Assume that ơ-7.70 ml/kg for the 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? What is the confidence interval?

State in words what the margin of error means for this problem, e.g. something like (for a proportion problem, which this is not) "with 90% confidence, we can state that between 1.4% and 3.8% of the parts manufactured are defective". c. Find the sample size necessary for a 99% confidence level with a maximal margin of error of E-2.50. Round UP to the nearest whole person. (SHOW WORK) (SHOW WORK) [final answer]: n-
