Consider the following observations on a receptor binding measure (adjusted distribution volume) for a sample of 13 healthy individuals: 22, 39, 40, 42, 43, 46, 50, 58, 63, 65, 67, 69, 71.A) Is it plausible that the population distribution from which this sample was selected is normal?B) Calculate an interval for which you can be 95% confident that at least 95% of all healthy individuals in the population have adjusted distribution volumes lying between the limits of the interval. C) Predict the adjusted distribution volume of a single healthy individual by calculating a 95% prediction interval. D) How does this interval's width compare to the width of the interval calculated in part (b)?
