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 random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (militers plasma per kilogram body weight). Assume that o = 7.20 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 (b) What conditions are necessary for your calculations? (Select all that apply.) O n is large O the distribution of volumes is uniform O o is known O a is unknown O 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 0.99. O we are 99% confident that the true average blood plasma volume in male firefighters falls within this interval. O we are 1% confident that the true average blood plasma volume in male firefighters falls within this interval.

Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
