Unformatted text preview: b. Verify that this is a valid probability distribution. c. Find the expected number and standard deviation of defective microcomputers. (3) Classify each of the following random variables as discrete or continuous: a. The number of automobile accidents per year in VA. b. The length of time to play 18 holes of golf. c. The amount of eggs laid each month by a hen. d. The weight of grain produced per acre. (4) Determine the value of c so that this function can serve as a probability distribution of the discrete random variable X. f(x) = c(x 2 +4) for x = 0, 1, 2, 3 (5) The probability distribution of X, the number of imperfections per 10 meters of a synthetic fabric in continuous rolls of uniform width, is given by X O 1 2 3 4 f(x) 0.41 0.37 0.16 0.05 0.01 Construct the cumulative distribution of X....
