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 a=.05, that the test scores in the web based self paced method are lower?

A) The data does not support the claim because the test value 1.27 is less than the critical value 1.65

B) The data does not support the claim because the test value 1.27 is less than the critical value 1.96

C) The data supports the claim because the test value 3.19 is greater than the critical value 1.96

D) The data supports the claim because the test value 3.19 is greater than the critical value 1.65 Explain.
