Two teaching methods and their effects on science test scores are being reviewed. A random sample of 12 students, taught in traditional lab sessions, had a mean test score of 75.6 with a standard deviation of 5.2. A random sample of 17 students, taught using interactive simulation software, had a mean test score of 84.3 with a standard deviation of 6.2. Do these results support the claim that the mean science test score is lower for students taught in traditional lab sessions than it is for students taught using interactive simulation software?
