Find the conditional distribution of y given x = 3 Find the conditional distribution of x given y = 2. Use the formulas that are in question 5.129, 7 th edition [ 5.109, 6 th edition ] in your book. You do not need to prove the formulas. Find the value of the correlation coefficient. E . The probability density function if the failure time of a pump is uniform (i.e. it has a constant value, k ) between 0 and 100 months and zero elsewhere. a) Find k b) Find and plot the hazard function, h(t) . c) Find the expected life of the pump....
