Test Scores An instructor who taught an online statistics course and a classroom course feels that the variance of the final exam scores for the students who took the online course is greater than the variance of the final exam scores of the students who took the classroom final exam. The following data were obtained. At =α0.05 is there enough evidence to support the claim? Use σ21 for the variance of the online scores. Use the critical value method and tables.
State the Hypothesis and Identify the claim: H0: Claim or not a claim H1: Claim or not a claim
Find the critical Value: Round the answer to at least two decimal places.
Compute the test value:
Make the decision reject or accept the null hypothesis.
Summarize the results. Is there enough evidence to support the claim?
