There is a huge debate going on in education about whether technology in the classroom is helpful or harmful to students. To settle the debate researchers use a sample of 10 students and taught them once material with technology and once material without technology. The tests and material were chosen to make it possible to test the impact of technology use on the learning abilities of the students. Calculate the mean of the matched pair-differences. (round to 1 decimal) · Calculate the standard deviation of the matched pair-differences. (round to 2 decimal places) · Calculate the test-statistic. (round to 2 decimal places) · Determine the critical value for alpha =0.01. (round to 2 decimal places)
