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 a = 0.10 is there enough evidence to support the claim? Use of for the variance of the online scores. Use the critical value method and tables.

Question

(i) Determine if the hypothesis test is one tailed or two tailed.

(ii) Find the critical value. Round the answer to at least two decimal places.

(iii) Compute the test value. Round the standard deviations and F-score values to two decimal places as needed.

(iv) Make the decision and summarize the results. 

**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 \( \alpha = 0.10 \), is there enough evidence to support the claim? Use \( \sigma^2_1 \) for the variance of the online scores. Use the critical value method and tables.

|                     | Online Course | Classroom Course |
|---------------------|--------------|------------------|
| Sample Variance \( s^2 \) | 2.7          | 2.5              |
| Sample Size \( n \)      | 13           | 21               |

Use the provided data to test the hypothesis using the appropriate statistical methods.
