question 1

Multiple Choice

Heidi runs a multiple regression for the output of cheese curds by using the daily temperature and the consumption of sweet clover.The intercept term is 23,the slope coefficient for the daily temperature is 1.5 and the slope coefficient for the consumption of sweet clover is 0.Which of these conclusions is most appropriate?

• A) Heidi should collect more data.
• B) The most important term in Heidi's model is the intercept.
• C) As the daily temperature rises, the intercept term probably decreases.
• D) Heidi should drop the sweet clover term from her model.
