7. Two bonding agents, A and B, are available for making a laminated beam. Of 50 beams made with Agent A, 19 failed a stress test, whereas 11 of the 50 beams made with agent B failed. If the alternative hypothesis is A + B, what is B, the probability of Type II error, for the above information if the type I error is 0.15? (5 points) 8. A production facility contains two machines that are used to rework items that are initially defectite. Let X be the number of hours that the first machine is in use, and let y be the number of hours that the second machine is in use, on a randomly chosen day. Assume that X and Y have joint probability density function given by, f(x, y) = (x² + y2) + 0<x< 1 and 0 < y < 1 elsewhere 0 What is the probability that both machines are in operation for more than half an hour? |(5 points)
