A researcher is trying to determine whether a new teaching technique is more effective than the old teaching technique. Two groups of student with 20 and 24 members were taken for 3 months to undergo with the two techniques. Results are shown below: Technique Мean SD New 82.45 6.95 20 old 80.97 7.50 24 Assume unequal variances. a.) Test the claim that the new technique is superior to the old at 0.01 level of significance. b.) Test the hypothesis that there is no significant difference between the new and old teaching techniques at 0.05 level of significance.
