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 a variance of s2=8, and the second treatment had M=52 and s2=4. Do these data indicate a significant difference between the two treatments? use a two-tailed test with α =.05. (Note: Because the two samples are the same size, the pooled variance is simply the average of the two sample variances.) Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all parts (including pooled variance) of the answers.
