Use computer software to find the regression equation. Can the equation be used for prediction?
-A wildlife analyst gathered the data in the table to develop an equation to predict the weights of bears. He used WEIGHT as the dependent variable and CHEST, LENGTH, and SEX as the independent variables. For SEX, he used male=1 and female=2.

\begin{array}{cccc}\hline \text { WEIGHT } & \text { CHEST } & \text { LENGTH } & \text { SEX } \\\hline 344 & 45.0 & 67.5 & 1 \\416 & 54.0 & 72.0 & 1 \\220 & 41.0 & 70.0 & 2 \\360 & 49.0 & 68.5 & 1 \\332 & 44.0 & 73.0 & 1 \\140 & 32.0 & 63.0 & 2 \\436 & 48.0 & 72.0 & 1 \\132 & 33.0 & 61.0 & 2 \\356 & 48.0 & 64.0 & 2 \\150 & 35.0 & 59.0 & 1 \\202 & 40.0 & 63.0 & 2 \\365 & 50.0 & 70.5 & 1 \\\hline\end{array}

A) WEIGHT

= - 320 + 10.6

CHEST + 7.3LENGTH - 10.7SEX; Yes, because the

\mathrm { P }

-value is high
B) WEIGHT

= - 442.6 + 12.1

CHEST + 3.6LENGTH

- 23.8

SEX; Yes, because the adjusted

R ^ { 2 }

is high
C) WEIGHT

= 442.6 + 12.1

CHEST

+ 4.2

LENGTH

- 21 S E X ;

Yes, because the P-value is low
D) WEIGHT

= 196 + 2.35

CHEST

+ 3.40

LENGTH

+ 25

SEX; Yes, because the

\mathrm { R } ^ { 2 }

is high
