Two teaching methods and their effects on science test scoresare being reviewed. A random sample of 16 16 students, taught intraditional lab sessions, had a mean test score of 80.8 80.8 with astandard deviation of 4.4 4.4 . A random sample of 14 14 students,taught using interactive simulation software, had a mean test scoreof 85.6 85.6 with a standard deviation of 5.1 5.1 . Do theseresults support the claim that the mean science test score is lowerfor students taught in traditional lab sessions than it is forstudents taught using interactive simulation software? Let μ1 μ 1be the mean test score for the students taught in traditional labsessions and μ2 μ 2 be the mean test score for students taughtusing interactive simulation software. Use a significance level ofα=0.05 α = 0.05 for the test. Assume that the population variancesare equal and that the two populations are normally distributed.Step 2 of 4 : Compute the value of the t test statistic. Round youranswer to three decimal places.
