Weekly CPU time used by an accounting firm has probability density function (measured in hours) given by

(a) Find the expected value and variance of weekly CPU time.

(b) The CPU time costs the firm 200$ per hour. Find the expected value and variance of the weekly cost for CPU time.

(c) Would you expect the weekly cost to exceed 600$ very often? Why?

Expert Solution

a) Find the expected value and variance of weekly CPU time.

(b) The CPU time costs the firm 200$ per hour. Find the expected value and variance of the weekly cost for CPU time.

c. Since E(c)=480sl so my expectation is the cost will be less than $600
