Two teaching methods and their effects on science test scores are being reviewed. A random sample of 6 students, taught in traditional lab sessions, had a mean test score of 75.7 with a standard deviation of 4.3. A random sample of 10 students, taught using interactive simulation software, had a mean test score of 83.4 with a standard deviation of 4.2. 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? Let μ₁ be the mean test score for the students taught in traditional lab sessions and μ₂ be the mean test score for students taught using interactive simulation software. Use a significance level of a = 0.01 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 2 of 4: Compute the value of the t test statistic. Round your answer to three decimal places.
