Chapter 1, Problem 19SP
In the following experiments, identify the independent variable, the conditions, and the dependent variable:
(a) studying whether final exam scores are influenced by whether concurrent background music is soft, loud, or absent;
(b) comparing students from small, medium, and large colleges with respect to how much fun they have during the semester;
(c) studying whether being first-, second-, or third-born is related to intelligence;
(d) studying whether length of daily exposure to a sunlamp (15 versus 60 minutes) accounts for differences in depression;
(e) studying whether being in a room with blue walls, green walls, or red walls influences aggressive behavior in adolescents.

The following are suggested designs for group sequential studies. Using PROCSEQDESIGN, provide the following for the design O’Brien Fleming and Pocock.• The critical boundary values for each analysis of the data• The expected sample sizes at each interim analysisAssume the standardized Z score method for calculating boundaries.Investigators are evaluating the success rate of a novel drug for treating a certain type ofbacterial wound infection. Since no existing treatment exists, they have planned a one-armstudy. They wish to test whether the success rate of the drug is better than 50%, whichthey have defined as the null success rate. Preliminary testing has estimated the successrate of the drug at 55%. The investigators are eager to get the drug into production andwould like to plan for 9 interim analyses (10 analyzes in total) of the data. Assume thesignificance level is 5% and power is 90%.Besides, draw a combined boundary plot (OBF, POC, and HP)
