A study was conducted to see if there was a linear relationship between the number of hours studied and exam scores.

The following table of values summarizes the data collected:

Hours Studied 0 1 2 3 4
Exam Score 50 63 65 81 99



Based on these data, compute a $99\%$ confidence for the slope of the regression line, β.

A

$-108.2 ≤β≤ -30.99$

B

$-81.18 ≤β≤ -58.02$

C

$2.206 ≤β≤ 20.99$

D

$6.4816 ≤β≤ 16.718$

E

$7.8151 ≤β≤ 15.385$
