There is more variability in the prediction interval of a single value of y than in the confidence interval of E(Y) b. There is less variability in the prediction interval of a single value of y than in the confidence interval of E(Y) c. There is no conclusive statement about the variability between the the two intervals. d. The two intervals always have equal variability
Show that for the distribution: dF(x) = 0 exp(-x0) ; 0 < x <∞, central confidence limits for large samples with 95% confidence coefficient are given by 0 = 1+ 1.96 1500)/I. X.
A random sample of size n1 = 15 is selected from a normal population with a mean of 75 and a standard deviation of 9. A second random sample of size n2 = 9 is taken from another normal population with mean 69 and standard deviation 15. Let X1 and X2 be the %3D two sample means.

Problem #4: (2 points) Find a 100(1 - a)% confidence interval for 0, given X₁,,X, i.i.d. with pdf f(x0) = 1,0-0.5 0.
This problem explores the question of estimating o(> 0) using a confidence interval based on a random sample X1, X2, ..., Xn from the distribution with pdf fo(x) = {& exp(- 20 if x > 0 otherwise. (a) Find the pdf of X2 by finding the cdf and differentiating it. (b) Using the result of (a) and techniques we developed in class, propose a pivot for estimating using a confidence interval and find the distribution of your pivot. Review Slides 38-41 of the power points for Chapter 7.1 to remind yourself how a pivot is used to construct a confidence interval. (c) Using the pivot obtained in (b) and the fact that o> 0, write down the formula for finding a short 100(1-a)% confidence interval for o. (d) Using the formula obtained in (c), compute the width of the resulting 95% confidence interval when n = 1 and ₁ = 1. (e) Is the 95% confidence interval for a you obtained in (d) when n = 1 and ₁ = 1 the shortest possible? If your answer is yes, explain why. If the answer is no, give a…
