Use Computer Software to Find the Regression Equation A) $\mathrm{CO}=1.3+5.5 \mathrm{TAR}-1.3 \mathrm{NIC}$

question 55

Multiple Choice

Use computer software to find the regression equation. Can the equation be used for prediction?
-An anti-smoking group used data in the table to relate the carbon monoxide of various brands of cigarettes to their tar and nicotine content. $\begin{array}{ccc}\hline\text { CO } & \text { TAR } & \text { NICOTINE } \\\hline 15 & 1.2 & 16 \\15 & 1.2 & 16 \\17 & 1.0 & 16 \\6 & 0.8 & 9 \\1 & 0.1 & 1 \\8 & 0.8 & 8 \\10 & 0.8 & 10 \\17 & 1.0 & 16 \\15 & 1.2 & 15 \\11 & 0.7 & 9 \\18 & 1.4 & 18 \\16 & 1.0 & 15 \\10 & 0.8 & 9 \\7 & 0.5 & 5 \\18 & 1.1 & 16\\\hline\end{array}$

• A) \( \mathrm{CO}=1.3+5.5 \mathrm{TAR}-1.3 \mathrm{NIC} \);
• Yes, because the adjusted \( R^{2} \) is high
• B) \( \mathrm{CO}=1.37+5.50 \mathrm{TAR}-1.38 \mathrm{NIC} \);
• Yes, because the \( \mathrm{P} \)-value is high
• C) \( \mathrm{CO}=1.25+1.55 \mathrm{TAR}-5.79 \mathrm{NIC} \);
• Yes, because the \( \mathrm{P} \)-value is too low
• D) \( \mathrm{CO}=1.37-5.53 \mathrm{TAR}+1.33 \mathrm{NIC} \);
• Yes, because the \( R^{2} \) is high
