An Educational Researcher Is Analyzing the Test Scores for Physics $\alpha = .05$

question 2

Multiple Choice

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 $\alpha = .05$ , that the test scores in the web-based self-paced method are lower?
$\begin{array}{lcc}\hline & \text { Traditional } & \text { Web-based Self-paced } \\\hline \text { Sample size } & 60 & 80 \\\text { Mean test score } & 86 & 83 \\\text { Population variance } & 24 & 34\end{array}$

• A) The data supports the claim because the test value 3.30 is greater than the critical value 1.65.
• B) The data supports the claim because the test value 3.30 is greater than the critical value 1.96.
• C) The data supports the claim because the test value 1.82 is less than the critical value 1.96.
• D) The data supports the claim because the test value 1.82 is greater than the critical value 1.65.
