Using the raw data, answer the following:

What are the scores of the pre-and post-test for the experimental group (group #'s 1&2)?

What are the scores of the pre-and post-test for the control group (group #'s 3&4)? Is there a significance using p < 0.05

Compare the different scores for the control and experiment groups pretest and posttest data?

Is the null hypotheses true?

H0: the experimental group showed greater results than the control group

H1: the experimental group is not more statistically significant than the control group
