Quadratic model

Quadratic Model X NOW UI OO - Meanx= 9 Meany= 4.6 SDx= 3.46 SDy= 2.06 r = 0.64 Slope (b) = 0.01 Intercept (a) = 4 2. Using the data and calculations provided above, calculate the R-squared value for the model below: Model 2 (quadratic): Y-hat = 4 + (.01*X^2) 3. Is model 1 or model 2 better? How do you know this
