Question

MY NOTES PRACTICE ANOTHER Consider the following observations on a receptor binding measure (adjusted distribution volume) for a sample of 13 healthy individuals: 24, 38, 40, 41, 43, 48, 51, 58, 63, 67, 68, 70, 72. (a) Is it plausible that the population distribution from which this sample was selected is normal? it is plausible that the population distribution is normal. Yes (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.) 43.272 X (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 than the width of the interval calculated in part (b). You may need to use the appropriate table in the Appendix of Tables to answer this question. Need Help?
