An educational researcher is analyzing the test scores for statistics students taught using two different methods - a traditional method and a web-based self-paced method. Can he conclude, at a = .05, that the test scores in the web-based self-paced method are lower? Traditional Web-based Self-paced Sample size 60 40 Mean test score 78 75 Sample variance 24 34 O The data does not support the claim because the test value 1.20 is less than than 1.64. O The data does not support the claim because the test value 1.20 is less than than 1.96. O The data supports the claim because the test value 2.68 is greater than than 1.96. The data supports the claim because the test value 2.68 is greater than than 1.64.
