The table shows the reduction in costs (in hundreds) after a manager found ways each month to cut back in his store. identify the best fit mathematical model with its corresponding r^2 value and tell whether it is a good model.
month: 1. 2. 3. 4. 5
profit loss: 86. 82. 72. 45. 15
a: quadratic model, 0.997
no 0.997 is too high an r^2 value.
b: quadratic model, 0.997
yes, 0.997 is very close to 1.
c. linear model, 0.902
no, 0.902 is too high an r^2 value.
d. linear model, 0.902
yes, 0.902 is very close to 1.
