Explanation / Answer

1) H0: There is not effect of cigarette prices on smoking
H1: There is effect of cigarette prices on smoking
The P-value of Cigarette Price is 0.0482 < alpha 0.05,
So, we reject H0, thus we conclude that there is effect of cigarette prices on smoking

2) H0: There is not effect of beer prices on smoking
H1: There is effect of beer prices on smoking
The P-value of beer Price is 0.2851 > alpha 0.05,
So, we do not reject H0, thus we conclude that there is not effect of beer prices on smoking

3) P-value of F = 1.662e-12 < alpha 0.05,
So, we reject H0, thus we conclude that all the variables are effect on smoking
i.e. the regression equation is best fit to the given data
