- You want to find out if developmental English courses had a positive affect on students' writing skills. You have a sample of 10 students do a writing sample the first day of class and on the last day of class. You want to determine if there is significant gains in writing ability at the 0.05 level.You believe the population of difference scores is normally distributed. You obtain the following sample of data: post-test pre-test 65.7 65.4 45.2 45.4 55 55.4 49 48.6 50.7 50.4 56 55.3 77.3 77.2 61.7 62 48.5 47.7 62.4 62 Use a 0.05 alpha level.
