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 α = .05, that the test scores in the web-based self-paced method are lower?
Traditional Web-based Self-paced
Sample size 50 40
Mean test score 80 76
Population variance 26 42
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.
