Question 729103: 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?
Traditional Web-based Self-paced
Sample size 50 70
Mean test score 80 76
Population variance 26 32
The data supports the claim because the test value 2.05 is greater than the critical value 1.65.
The data supports the claim because the test value 2.05 is greater than the critical value 1.96.
The data supports the claim because the test value 4.05 is greater than the critical value 1.96.
The data supports the claim because the test value 4.05 is greater than the critical value 1.65.
