Q2. A researcher specified regression model , in order to
estimate effect of fertilizers and insecticides on corn production. Data for 10 years is
summarized below:
Where Y= bushels of corn per acre, X1 = amount of fertilizer in pounds per acre and
X2 = amount of insecticides in pounds per acre
i. Fit OLS regression equation and interpret it
ii. Using fitted regression equation, predict bushels of corn per acre produced if
amount of fertilizers used per acre is 30 pounds and amount of insecticides used
per acre is 8 pounds
iii. Calculate R2
and interpret it.

Farmer Hoglund has discovered that on his farm, he can get 30 bushels of corn per acre if he applies no fertilizer. When he applies N pounds of fertilizer to an acre of land, the marginal product of fertilizer is 1 − N/200 bushels of corn per pound of fertilizer. (a) If the price of corn is $3 a bushel and the price of fertilizer is $p per pound (where p < 3), how many pounds of fertilizer should he...

For several years, farmers in Nebraska have kept track of the amount of rainfall (in inches) and the amount of corn produced (in bushels per acre). A strong and linear relationship has been observed between these variables. When a regression equation is constructed in order to predict amount of corn produced based on rainfall, it is found that the equation has an intercept of 89.54 and a slope of 0.13. From this information, we can conclude that A as amount...

3.3 Breakfast cereals. A regression model was fit to a sample of breakfast cereals. The response variable Y is calories per serving. The predictor variables are X1, grams of sugar per serving, and X2, grams of fiber per serving. The fitted regression model is Y 109.3 +1.0.Xi -3.7 X2 In the context of this setting, interpret -3.7, the coefficient of X2. That is, describe how fiber is related to calories per serving, in the presence of the sugar variable.

The equation used to predict the total body weight (in pounds) of a female athlete at a certain school is y=−118+3.54x1+1.47x2, where x1 is the female athlete's height (in inches) and x2 is the female athlete's percent body fat, measured as x2%. Use the multiple regression equation to predict the total body weight for a female athlete who is 63 inches tall and has 15% body fat. The predicted total body weight for a female athlete who is 63 inches...
