Two teaching methods and their effects on science test scores are being reviewed.

A random sample of 11 students, taught in traditional lab sessions, had a mean test score of 76.7 with a standard deviation of 3.2.

A random sample of 16 students, taught using interactive simulation software, had a means test score of 83.2 with a standard deviation of 6.4.

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?Use a significance level of= 0.1 for the test.

(Assume that the population variances are not equal, i.e. set "pooled" to "no.")

Name at least two inferential statistics used in this problem.
