Question:

The thickness X of a wooden shim (in mm) has probability density function.

3(x - 5)? 4 = (x)/ 4 <x<6 f(1) = otherwise

a. Find Î¼_X.

b. Find Ïƒ²_X.

c. Let Y denote the thickness of a shim in inches (1 mm = 0.0394 inches). Find Î¼Y and Ïƒ²_Y.

d. If three shims are selected independently and stacked one atop another, find the mean and variance of the total thickness.
