question 88

Multiple Choice

The data below are the temperatures on randomly chosen days during a summer class and the number of absences on those days. Find the equation of the regression line for the given data. $$\begin{array} { l | c | c | c | c | c | c | c | c | c | } \text { Temperature, } \mathrm { x } & 72 & 85 & 91 & 90 & 88 & 98 & 75 & 100 & 80 \\\hline \text { Number of absences, } \mathrm { y } & 3 & 7 & 10 & 10 & 8 & 15 & 4 & 15 & 5\end{array}$$

• A) \( \hat { \mathrm { y } } \) = 0.449x - 30.27
• B) \(\hat { y }\) = 30.27x - 0.449
• C) \(\hat { \mathrm { y } }\) = 0.449x + 30.27
• D) \(\hat { y }\) = 30.27x + 0.449
