Multiple Choice

An anti-smoking group used data in the table to relate the carbon monoxide output of various brands of cigarettes to their tar and nicotine content. $$\begin{array} { c c c } \text { CO } & \text { Tar } & \text { Nicotine } \\\hline 15 & 1.2 & 16 \\15 & 1.2 & 16 \\17 & 1.0 & 16 \\6 & 0.8 & 9 \\1 & 0.1 & 1 \\8 & 0.8 & 8 \\10 & 0.8 & 10 \\17 & 1.0 & 16 \\15 & 1.2 & 15 \\11 & 0.7 & 9 \\18 & 1.4 & 18 \\16 & 1.0 & 15 \\10 & 0.8 & 9 \\7 & 0.5 & 5 \\18 & 1.1 & 16\end{array}$$

• A)CO = 1.25 + 1.55 Tar - 5.79 Nicotine
• B)CO = 1.38 - 5.53 Tar + 1.33 Nicotine
• C)CO = 1.38 + 5.50 Tar - 1.38 Nicotine
• D)CO = 1.27 - 5.53 Tar + 5.79 Nicotine
• E)CO = 1.30 + 5.50 Tar - 1.33 Nicotine
