Solutions

Expert Solution

(a)

Density of an Exponential Distribution is given by:

,                         (1)

                               for x 0

         = 0 for x < 0

(b)

Step 1:

Moment Generating Function is given by:

                             (2)

Step 2:

Substituting (1) in (2), we get:

      between limits 0 to

Step 3;

Applying limits, we get:

Thus, answer is:

,
