That can be known based on the results of the pre-test and post-test. with the comparison of the magnitude of t that we get in the manual counting (t0) = 12,59 and the magnitude of t listed in the table of values (t.ts.5% = 2.03), we can know that t0 is greater than tt .2.03 > 12,59. So it can be concluded that the hypothesis is accepted or Ha is accepted, while Ho is rejected. descriptive writing.
