Question: Engelbert Humperdink, a master teacher at Campbell Elementary School has decided that the out-of-seat behavior time in his fifth grade class was intolerable. In order to treat this "Attention Deficit Disorder", he randomly selects 35 students from her morning class and gives them 18mg of Ritalin and he randomly selects 42 students from her afternoon class and gives those 10mg of Adder all ax. After several months of clinical evaluation he computes his findings, namely that the average out of seat behavior time for students who were on Ritalin was 17 minutes/per 45 minute period and the students who were on Adder all ax had an average of 21 minutes/per 45 minute period out of seat time. The population standard deviations were obtained from each of the pharmaceutical companies: Ritalin has a 4.8 minutes standard deviation per 45 minute period and Adder all ax has a 5.9 minutes standard per 45 minute period. At a one percent significance level test the claim that Ritalin is superior in relieving Attention Deficit Disorder than its counterpart, Adder all ax, Assume the population standard deviation is known.
