An educational researcher is analyzing the test scores for physics students taught using two different methods - a traditional method, and a web-based self-paced method. Can he conclude, at = .05, that the test scores in the web-based self-paced method are lower?
A) The data supports the claim because the test value 1.68 is greater than than the critical value 1.65.
B) The data supports the claim because the test value 1.68 is less than than the critical value 1.96.
C) The data supports the claim because the test value 3.66 is greater than than the critical value 1.96.
D) The data supports the claim because the test value 3.66 is greater than than the critical value 1.65.
