Question

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 46 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 = 8.00 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? (Round your answers to two decimal places.)

lower limit

upper limit

margin of error

(d) Find the sample size necessary for a 99% confidence level
with maximal margin of error E = 2.60 for the mean plasma volume in
male firefighters.

Answer #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 41 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 = 7.10
ml/kg for the distribution of blood plasma.
