Consider the following observations on a receptor binding measure (adjusted distribution volume) for a sample of 13 healthy individuals: 22, 40, 41, 42, 43, 46, 51, 59, 62, 67, 68, 70, 71. (a) Is it plausible that the population distribution from which this sample was selected is normal? Yes Correct: Your answer is correct. , it is Correct: Your answer is correct. plausible that the population distribution 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. (Round your answers to three decimal places.) , (c) Predict the adjusted distribution volume of a single healthy individual by calculating a 95% prediction interval. (Round your answers to three decimal places.) , How does this interval's width compare to the width of the interval calculated in part (b)? This interval's width is less Correct: Your answer is correct. than the width of the interval calculated in part (b).
