n = sample size = 45
Sample mean =
Population standard deviation =
Here population standard deviation is known so we use here z interval
a) Confidence level = c = 0.99
99% confidence interval for population mean blood plasma volume in male fire fighters is
where zc is z critical value for (1+c)/2 = (1+0.99)/2 = 0.995
zc = 2.58 (From statistical table of z values)
(Round to 4 decimal)
99% confidence interval for population mean blood plasma volume in male fire fighters is (34.6155, 40.3845)
b) Margin of error (E)
E = 2.88 (Round to 2 decimal)
Margin of error is 2.88
c) Margin of error = 2.50
n = 59.9076
n ~ 60 (Round to nearest integer)

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 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 σ = 7.40 ml/kg for the distribution of blood plasma. (a) Find a...

Allen's hummingbird (Selasphorus sasin) has been studied by zoologist Bill Alther.† Suppose a small group of 18 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x = 3.15 grams. Based on previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with σ = 0.36 gram. (a) Find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of...
