SOLUTION
The equation of line of best fit is
[tex]y=-0.76x+26.04[/tex]
a. substitute x=12 into the equation
[tex]y=-0.76(12)+26.04[/tex]
Calculate the value of y
[tex]\begin{gathered} y=-9.12+26.04 \\ y=16.92 \end{gathered}[/tex]
The predicted time spent is 16.92 hours
b. For those who spent no time is 26.04
c. The right answer is
[tex]-0.76[/tex]
