Provide an appropriate response. Ten families are randomly selected and their daily water usage (in gallons) is measured before and after viewing a conservation video. Calculate the test statistic and state your conclusion for testing Ho: Ha-0 versus Ha Ha 0 where the difference is "before" minus "after". Assume x d-4.8, S-5.2451 anda -0.05 -0.92. Fail to reject the null hypothesis. There is insufficient evidence o conclude that the mean daily water usage decreased following the viewing of the conservation video. -2.89. Fail to reject the null hypothesis. There is insufficient evidence to conclude that the mean daily water usage decreased following the viewing of the conservation video. -0.92. Reject the null hypothesis and conclude that the mean daily water usage decreased following the viewing of the conservation video. -2.89. Accept the null hypothesis and conclude that there is no difference in the mean daily water usage before and after viewing the conservation video. -2.89. Reject the null hypothesis and conclude that the mean daily water usage decreased following the viewing of the conservation video.
