suppose that the number of defects in a 1200-foot roll of magnetic recording tape has a Poisson distribution for which the value of the mean 0 is unknown, and the prior distribution of 0 is a gamma distribution with parameters =3 and =1 when five rolls of this tape are selected at random and inspected, the numbers of defects found on the roll are 2,2,6,0, and 3. Determine the posterior Distribution of 0
