Please confirm the values for
year = 0 as it is lower than after a year on, do you think a computer can appreciate?
year = 1 is the comma in the correct place? Should it be 1,200?
year = 3, should this be 1,000?
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
