15.3 Suppose our prior belief is u is just as likely to be below 8 as it is to be above 8. (Our prior distribution g(o) has median 8.) Determine an Sx an inverse chi-squared(&) that matches our prior median where we use R = 1 degree of freedom.

(a) Find the posterior using the Minitab macroNKarlCf!rnac or the equivalent R function.
