Two methods for teaching reading were applied to two randomly selected groups of elementary schoolchildren and then compared on the basis of a reading comprehensive test given at the end of the learning period. The results are given in the following table. Method I Method II Sample size Mean 11 14 64 69 variance 52 71 Do the data present sufficient evidence to indicate a difference in the mean scores for the populations associated with the two teaching methods? What can be said about the attained significance level? What assumptions are required? Check your assumption by an appropriate method. What would you conclude at the 5% level of significance?

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
