Interpret the Coefficients of a Multiple Regression Equation
-Given the regression equation that relates a student's weight to the number of hours spent on the computer, $x$ , the number of hours viewing television, $x 2$ , and the number of hours on their cell phone, $x _ { 3 }$ , per day as $\hat { \mathrm { y } } = 125.5 + 3.26 \mathrm { x } _ { 1 } + 4.27 \mathrm { x } _ { 2 } + 1.75 \mathrm { x } _ { 3 }$ . What is a student's expected weight change if the amount of television is increased by 1 hour, the number of hours watching television and talking on their cell phone stayed the same?

A) $4.27$ pounds
B) $3.26$ pounds
C) $1.75$ pounds
D) $125.5$ pounds
