Consider the following data for two variables, x and y. 32 18 15 26 y 11 | 19 20| 17 | 21 (a) Develop an estimated regression equation for the data of the form ý = b, + b,x. (Round b, to two decimal places and b, to three decimal places.) Comment on the adequacy of this equation for predicting y. (Use a = 0.05.) O The high p-value and low coefficient of determination indicate that the equation is inadequate. O The high p-value and high coefficient of determination indicate that the equation is adequate. O The low p-value and low coefficient of determination indicate that the equation is inadequate. O 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 ý = b, + b,x + b,x². (Round b, to two decimal places and b, to three decimal places and b, to four decimal places.) タ= Comment on the adequacy of this equation for predicting y. (Use a = 0.05.) O The high p-value and low coefficient of determination indicate that the equation is inadequate. O The high p-value and high coefficient of determination indicate that the equation is adequate. O The low p-value and low coefficient of determination indicate that the equation is inadequate. O The low p-value and high coefficient of determination indicate that the equation is adequate. (c) Use the model from part (b) to predict the value of y when x = 20. (Round your answer to two decimal places.)
