Two teaching methods and their effects on science test scores are being reviewed. A random sample of 77 students, taught in traditional lab sessions, had a mean test score of 79.679.6 with a standard deviation of 3.33.3. A random sample of 1515 students, taught using interactive simulation software, had a mean test score of 84.984.9 with a standard deviation of 55. 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�1 be the mean test score for the students taught in traditional lab sessions and μ2�2 be the mean test score for students taught using interactive simulation software. Use a significance level of α=0.05�=0.05 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 3 of 4 : Determine the decision rule for rejecting the null hypothesis H0�0. Round your answer to three decimal places.
