report the null and alternative hypotheses, report the test statistics including post-hoc tests if appropriate (e.g., F(df, df) = x, p = x; t(df) = x, ptukey = x), make a statistical determination, and write 1-2 sentences explaining the results of the study. Javier is interested in how different types of exercise can affect academic performance. He will compare the math test performance of three different groups of students who were randomly assigned to exercise every day for a week in one of the following ways: swimming, dancing, or running. These groups will also be compared to a no-exercise group. Their scores on the final test at the end of the week are as follows. Swimming: 98, 77, 86, 79, 88, 92 Dancing: 89, 87, 91, 81, 93, 79 Running: 88, 77, 98, 68, 99, 87 No Exercise: 75, 79, 73, 80, 82, 65
