The accompanying table provides data for tar, nicotine, and carbon monoxide (CO) contents in a certain brand of cigarette. Find the best regression equation for predicting the amount of nicotine in a cigarette. Why is it best? Is the best regression equation a good regression equation for predicting the nicotine content? Why or why not? Click the icon to view the cigarette content data. C Find the best regression equation for predicting the amount of nicotine in a cigarette. Use predictor variables of tar and/or carbon monoxide (CO). Select the correct choice and fill in the answer boxes to complete your choice. (Round to three decimal places as needed.) A. Nicotine= CO OB. Nicotine = + Tar+(co OC. Nicotine= + Tar Why is this equation best? OA. It is the best equation of the three because it has the highest adjusted R², the lowest P-value, and only a single predictor variable. OB. It is the best equation of the three because it has the highest adjusted R², the lowest P-value, and removing either predictor noticeably decreases the quality of the model. OC. It is the best equation of the three because it has the lowest adjusted R², the highest P-value, and only a single predictor variable. OD. It is the best equation of the three because it has the lowest adjusted R2, the highest P-value, and removing either predictor noticeably decreases the quality of the model. Is the best regression equation a good regression equation for predicting the nicotine content? Why or why not? OA. Yes, the small P-value indicates that the model is a good fitting model and predictions using the regression equation are likely to be accurate. B. No, the large P-value indicates that the model is not a good fitting model and predictions using the regression equation are unlikely to be accurate. C. No, the small P-value indicates that the model is not a good fitting model and predictions using the regression equation are unlikely to be accurate. D. Yes, the large P-value indicates that the model is a good fitting model and predictions using the regression equation are likely to be accurate.
