(a) Let X,, N. X be a random sample of size 10 from N(0, o). Find a conslal .... A so that R A(X,-X)/ V has a t-distribution. How many degrees of freedom are associated with the t-distribution? Suppose the mean of the nomal distribution is unknown, explain the effect on R. What changes, if any, would you make on R in order for it to follow a t-distribution? (b) Find P(2y² -32Y +127.968 s0) if Y has a normal distribution with µ-8 and o - 1. (c) Let S' be the variance of a random sample of size 21 from a normal distribution with mea riance 40 Find P6282 < S < 68.34).

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
