Consider the data set below. x 5 7 2 4 3 9 y 8 6 2 7 5 7 For ahyopthesis test, where H0:?1=0 and H1:?1?0, and using ?=0.05, givethe following:

(a) The test statistic t=

(b) The degree of freedom df=

(c) The rejection region |t|>

The final conclustion is

A. We can reject the null hypothesis that ?1=0 and accept that?1?0.

B. There is not sufficient evidence to reject the nullhypothesis that ?1=0.
