4.2.1. Let Y have a chi-square distribution with 15 degrees of freedom. Find the following probabilities. (a) P (Y <yo) = 0.025 (b) P(a <Y <b) = 0.95 (c) P (Y > 22.307).
4.2.2. Let Y have a chi-square distribution with 7 degrees of freedom. Find the following probabilities. (a) P(Y > yo) = 0.025 (b) P(a <Y <b) = 0.90 (c) P(Y > 1.239). 4.2.3. The time to failure T of a microwave oven has an exponential distribution with pdf f(0) = že-/2, If three such microwave ovens are chosen and 7 is the mean of their failure times, find the following: (a) Distribution of T. (b) P(T > 2). -1/2, 1>0.
