(A) Find the equation of the regression line that represents thenumber of full-time faculty, F , as a function ofx years since 2000. (round the regression coefficients totwo decimal places)
F(x) =
(B) What is the correlation coefficient (r-value) for theregression model? (Round your answer to three decimal places)
r =
(C) Given the value of r , does the regression line modelthe data well? That is, does the equation do a good job of modelingthe data?
Yes, the r-value is low, meaning the data can be modeled using aline
No, the r-value is high, meaning the data can't be modeled usinga line   Â
Yes, the r-value is high, meaning the data can be modeled usinga line
No, the r-value is low, meaning the data can't be modeled usinga line
(D) Using the regression line, How many Faculty members did WVUhave in 2010? (Round your answer to the nearest whole number)
