Find the p-value. (Round your answer to four decimal places.) p-value = 0
Is the addition of the interaction term and the smoker variable significant?
O Reject Ho. We conclude that the addition of the two independent variables are statistically significant. O Reject Ho. We conclude that the addition of the two independent variables are not statistically significant. O Do not reject Ho. We conclude that the addition of the two independent variables are statistically significant. O Do not reject Ho. We conclude that the addition of the two independent variables are not statistically significant.
