year Value ($) 0 1,500 1 1,1200 2 1,100 3 1,00 4 800 5 400 6 200

b. given that the equation of the regression line between value and year is y= -207.14x + 1507.14 with an R^2 value of 0.9622, how reliable do you think the regression equation is at predicting the future value of a computer in 5 years time?

c. calculate the value of the correlation coefficient between year and value

d. estimate the value of the computer in year 7, using the regression equation
