Two teaching methods and their effects on science test scores are being reviewed. A group of students is taught using interactive simulation software. A second group of students is taught in traditional lab sessions. The science test scores for the two groups are given below. At α = 0.05, can you support the claim that the mean science test score is higher for students taught using the interactive software than it is for students taught using the traditional lab method? Assume the samples are random and independent, the populations are normally distributed and assume the population variances are equal.
