8) 4.3.3(219) Use a computer package to find both the probability density function and cumulative distribution function at x = 3 and the median of gamma distribution with the following parameter values:
(a) k = 3.2, y = 0.8
(b) k = 7.5, y = 5.3
(c) k = 4.0, y = 1.4
In part (c) , check the value of the probability density function from its formula.
