Suppose y1Y2y25 is a random sample from a normal population
     Suppose y1,Y2.....y25 is a random sample from a normal population with mean mu ghama and  variance sigma^2 ghama and suppose further that x1,x2...x16 Is a random sample from a normal population with mean fix mu x and variance sigma^2 x. If the two samples are independent,  find a b such that P(1/sigma^2x 16 epsilon i =1 (xi - mu x)^2  c) = 0.95  9.31223, -0.0873
