A Company Is Researching the Effectiveness of a New Website

A company is researching the effectiveness of a new website design to decrease the time to access
A website. Five website users were randomly selected, and their times (in seconds) to access the
Website with the old and new designs were recorded. To compare the times, they computed (new
Website design time - old website design time) . The results follow:
If the calculated test statistic is -2.256, what is the decision regarding the hypothesis that the
Training was effective in improving customer relationships when tested at a 0.01 significance level?

A) Reject the null hypothesis and conclude that the new design reduced mean access times.
B) Reject the null hypothesis and conclude that the new design did not reduce mean access times.
C) Fail to reject the null hypothesis.
D) Fail to reject the null hypothesis and conclude that the mean access times are inaccurate.
