Suppose the relationship between applied stress x and time-to-failure Y is
described by the simple linear regression model with true regression line
E(y)=100-3.92x and σ2 =2. Let Y1 denotes an observation on time-to-failure
made with x=15 and Y2 denotes an independent observation made with x=14, find
the probability that Y1 exceed Y2, i.e.,P(Y1>Y2)=?
請問上述問題該如何解?
