Answer for the question:
Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information:x 1 2 3 4 5y 14 18.9 14.4 19.6 20.0 (a) Draw a scatter diagram. (3 points)(b) Find the equation of the least-squares line, and plot the line on the scatter diagram of part (a). (3 points)(c) Find the correlation coefficient r. Find the coefficient of determination . What percentage of variation in y is explained by the variation in x and the least squares model? (4 points)

Explanation:
Equivalent annual cost method is a capital budgeting method used to choose between two projects with an unequal life span
The decision rule is to choose the product with the higher Equivalent annual cost
Equivalent annual annuity method is better for making this decision because if net present value is used, the project with the higher useful life would be chosen. this does not mean it is more profitable
EAA =
Net present value is the present value of after-tax cash flows from an investment less the amount invested.
NPV can be calculated using a financial calculator
Machine A
Cash flow in year 0 = - $5,000
Cash flow in year 1 = $800
Cash flow in year 2 = $900
Cash flow in year 3 = $1,000
I = 9%
NPV A = -2736.35
Machine B
Cash flow in year 0 = -$6,000
Cash flow in year 1 = $850
Cash flow in year 2 = $900
I = 9%
NPV B = -4462.67
EAA =
(0.09 x -2736.35) / ( 1 - (1.09)^3) = $-1081.01
(0.09 x -4462.67) / ( 1 - (1.09)^2)= $-2536.89
