He decides go through with making his experiment arepeated-measures design. Each of the 20 subjects take part in bothconditions, and he finds a mean of the difference scores is 12(MD = 12) with a standard deviation of the differencescores of8Â Â Â Â Â Â Â Â Â Â (SD= 8). Please find the t-critical and the test statistic (assumingalpha = .052 tail). Then describe what the found.
