3. Color and Cognition. Researchers from the University of British Columbia conducted a study to investigate the effects of color on cognition tasks. Words were displayed on a computer screen with background colors of red and blue. Results from scores on a test of word recall are given below. Higher scores correspond to greater word recall. Red background Blue background n1 = 35, x, = 15.89, S1 = 5.90 n2 = 36, x2 = 12.31, S2= 5.48 b) Use a 0.05 significance level to test the claim that the samples are from populations with the same mean.
