Comment on the adequacy of this equation for predicting y. (Use a =
0.05.)
The high p-value and low coefficient of determination indicate that the equation is inadequate.
The high p-value and high coefficient of determination indicate that the equation is adequate.
The low p-value and low coefficient of determination indicate that the equation is inadequate.
The low p-value and high coefficient of determination indicate that the equation is adequate.
(b) Develop an estimated regression equation for the data of the form ŷ = bo + b,x + b,x². (Round b, to two decimal places and b, to three decimal places and b, to four decimal places.)
