Let X have a uniform distribution U(0, 2), and let the conditional distribution of Y, given that X = x, be U(0, x2). (a) Determine f (x, y), the joint pdf of X and Y. (b) Calculate fY(y), the marginal pdf of Y. (c) Compute E(X | y), the conditional mean of X, given that Y = y. (d) Find E(Y | x), the conditional mean of Y, given that X = x.

Exercises The American Association of Individual Investors (AAII) On-Line Discount Broker Survey polls members on their experiences with electronic trades handled by discount brokers. As part of the survey, members were asked to rate their satisfaction with the trade price and the speed of execution, as well as provide an overall satisfaction rating. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker, summary scores were computed by computing a weighted average of the scores provided by each respondent. A portion of the survey results follows (AAII website, February […]

Using the sample statistics, construct a 99%confidence interval estimate of the mean body temperature of all healthy humans. Do the confidence interval limits contain 98.6 degrees°F? What does the sample suggest about the use of 98.6  degrees°F as the mean body temperature? x= 98.5 degrees°F s = 0.61 degrees°F Best point estimate = 98.5 degrees°F What is the confidence interval estimate of the population mean μ? _____ degrees°F <  μ < ___________ degrees°F

Suppose that 10% of the adult population has blood chemistry parameters consistent with a diagnosis of a pre-diabetic condition. Of four volunteer participants in a health screening study, what is the probability that one of them is pre-diabetic?
