The SAT scores (out of a maximum possible score of 1600) for a random sample of 10 students who took this test recently are:
1355 765 890 1089 986 1128 1157 1065 1224 567
Test the hypothesis that the median SAT score is 1000 against the alternative that it is greater using α = 0.05. Use both the sign test and the Wilcoxon signed rank test. Explain if the conclusions are different.
