To test whether or not the population regression function is linear rather than a polynomial of order r:.A) check whether the regression R2 for the polynomial regression is higher than that of the linear regression. B) compare the TSSfrom both regressions. C) look at the pattern of the coefficients: if they change from positive to negative to positive, etc., then the polynomial regression should be used. D) use the test of (r-1) restrictions using the F-statistic.

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
