Assume that the paired date came from a population that is normally distributed. Using a .05 significance level, find d, Sd, the test t statistic, and the critical values to test the claim that Ud=0. x 7 10 12 12 3 15 17 8 y 12 12 7 8 8 11 12 5 d= Sd= t= t a/2 = +- Round all to three decimal places. Thank you in advance!! Solution.
