Solve the Problem Using Your Calculator $\begin{array} { l | r r r r r r } \text { Hours } & 5 & 10 & 4 & 6 & 10 & 9 \\\hline \text { Score } & 64 & 86 & 69 & 86 & 59 & 87\end{array}$

question 156

Short Answer

Solve the problem using your calculator.
-The paired data below consist of the test scores of 6 randomly selected students and the number of hours they studied for the test. Use a graphing calculator to model the data with a linear function that predicts a student's score as a function of the number of hours he or she studied.
$\begin{array} { l | r r r r r r } \text { Hours } & 5 & 10 & 4 & 6 & 10 & 9 \\\hline \text { Score } & 64 & 86 & 69 & 86 & 59 & 87\end{array}$
A) y=33.7+2.14x
B) y=33.7-2.14x
C) y=67.3+1.07x
D) y=-67.3+1.07x

• A) y=33.7+2.14x
