Question 5 (1 point)

A multiple regression analysis based on a data set that consists of 30 observations yielded the following estimated equation: Q = 120 - 1.1P + 3.7I + 0.09A where P is price, I is income, and A is advertising. The coefficient of determination (or R²) is 0.80, the F statistic is 34.7 and the p-value for the F statistic is 0.0037. From this information we can conclude

Question 5 options:

a)	that the true value of intercept term is 0.

b)	each of the estimated coefficients on Price, Income, and Advertising are not = 0.

c)	at least one of the estimated coefficients on Price, Income, and Advertising is not = 0.

d)	at least one of the estimated coefficients on Price, Income, and Advertising must = 0.
