Twenty quarterbacks were selected for this data. Summary data is as follows for the linear equation $y = a+bx$.

$b = 0.6776$
$a = 0.2305$
${ SE }_{ b }= 0.08807$*

A $99\%$ linear regression $T$-interval

A

Captures $1$, which fails to give evidence of any positive correlation between current year and previous year fantasy points.

B

Does not capture $0$, failing to give evidence of a positive linear relationship.

C

Does not capture $1$, failing to give evidence of any positive linear correlation between current year and previous year fantasy points.

D
