Question 2

Multiple Choice

Use computer software to find the multiple regression equation. Can the equation be used for prediction? An anti-smoking group used data in the table to relate the carbon monoxide (CO) of various brands of cigarettes to
Their tar and nicotine (NIC) content.  CO  TAR  NIC 151.216151.216171.01660.8910.1180.88100.810171.016151.215110.79181.418161.015100.8970.55181.116\begin{array}{ccc}\hline \text { CO } & \text { TAR } & \text { NIC } \\\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) CO=1.3+5.5TAR1.3NIC\mathrm { CO } = 1.3 + 5.5 \mathrm { TAR } - 1.3 \mathrm { NIC } ; Yes, because the adjusted R2R ^ { 2 } is high.
B) CO=1.375.53TAR+1.33NIC\mathrm { CO } = 1.37 - 5.53 \mathrm { TAR } + 1.33 \mathrm { NIC } ; Yes, because the R2R ^ { 2 } is high.
C) CO=1.37+5.50TAR1.38NIC\mathrm { CO } = 1.37 + 5.50 \mathrm { TAR } - 1.38 \mathrm { NIC } ; Yes, because the PP -value is high.
D) CO=1.25+1.55TAR5.79NIC\mathrm { CO } = 1.25 + 1.55 \mathrm { TAR } - 5.79 \mathrm { NIC } ; Yes, because the PP -value is too low.
