Consider the data set below.

$x$	$3$	$3$	$9$	$3$	$5$	$5$
$y$	$6$	$8$	$5$	$7$	$6$	$7$

For a hypothesis test, where $H_0:\beta_1 = 0$ and $H_1:\beta_1 \ne 0$, and using $\alpha = 0.05$, give the following:
(a) $\ $ The test statistic

$t =$
(b) $\ $ The degree of freedom

$df =$
(c) $\ $ The rejection region

$|t| >$
The final conclustion is

A. There is not sufficient evidence to reject the null hypothesis that $\beta_1 = 0$.
B. We can reject the null hypothesis that $\beta_1 = 0$ and accept that $\beta_1 \ne 0$.
