Two teaching methods and their effects on science test scores
are being reviewed. A random sample of 15 students, taught in
traditional lab sessions, had a mean test score of 71.7 with a
standard deviation of 5. A random sample of 17 students, taught
using interactive simulation software, had a mean test score of
76.1 with a standard deviation of 4.8. 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 α=0.05 for the test. Assume
that the population variances are equal and that the two
populations are normally distributed.
Step 3 of 4 :
Find the p-value for the hypothesis test. Round your answer
to four decimal places.
