A statistical analyst for the Wall Street Journal randomly selected six companies and recorded both the price per share of stock on January 1, 2009 and on April 30, 2009. The results are presented below. Suppose the analyst wished to see if the average price per share of stock on April 30, 2009 is greater than the average price per share of stock on January 1, 2009 at α=.05.

Apr. 30, 2009   35   38   26   29   30   34
Jan. 1, 2009   28   30   27   24   30   20

For the hypothesis stated above, what is the decision (in terms of "April 30, 2009" minus "January 1, 2009")?

a.

Fail to reject H0 because the test statistic is to the right of the positive critical value

b.

Reject H0 because P-value > α

c.

Fail to reject H0 because P-value > α

d.

None of the answers is correct

e.

Reject H0 because the test statistic is to the right of the positive critical value
