reject to nit 62 A résearcher 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: 7. Technique New Old Mean 82.45 80.97 Treatment No Treatment 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. SD 6.95 7.50 To find out whether a new serum will arrest leukemia, 9 mice, which have all reached an advanced stage of the disease, are selected. Five mice receive the treatment and 4 do not. The survival times in years from the time the experiment commenced are as follows: 2.1 1.9 5.3 0.5 n 20 24 1.4 2.8 4.6 3.1 Assume equal variances. Can we conclude that the serum is effective at 0.05 level of significance?
