Consider a proposed ultrasound inspection device for which the optimistic, and most likely, pessimistic estimates are given in Table 11-1. The MARR is 8% per year. Also shown at the following table are the AWs for all three estimation conditions. Based on this information, analyze the combined effects of uncertainty in the factors on the AW value.please do this in excel ~thank you~

	Optimistic (O)	Most Likely (ML)	Pessimistic (P)
Capital investment	$12,000	$15,000	$18,000
Useful life	18 years	10 years	8 years
Market value, MV	1000	500	0
Annual revenues, R	$110,000	70,000	50,000
Annual expenses, E	$20,000	$43,000	$57,000
