An independent-measures research study was used to compare two treatment conditions with n= 12 participants in each treatment. The first treatment had a mean of M= 55 with variance s2 = 8, and the second treatment had M= 52 and s2= 4.
a) Use a two-tailed test with Alpha= 0.05 to determine whether these date indicate a significant difference between the two treatments.
b) Use a two-tailed test with Alpha= 0.01 to determine whether these date indicate a significant difference between the two treatments.
c) Use a one-tailed test with Alpha= 0.05 to determine whether these date indicate a significant difference between the two treatments.
