For number 12-15: A doctor is interested in determining whether a fllm about exercise will change 10 persons' attitudes toward exercise. A survey was administered to determine the responses (on attitudes toward exercise) before and after the program.

Question
For number 12-15: A doctor is interested in determining whether a film about exercise will change 10 persons' attitudes toward exercise. A survey was administered to determine the responses (on attitudes toward exercise) before and after the program. Is there enough evidence to support the claim, at a= 0.05, that there was a change in attitude? Paired Differences Std. Mean Deviation Pair 1 Before After 3.000 1.39941 Std. Error Mean t df 0.44222 6.593 9 Sig. (2- tailed) 0.000 12. Which mean score is lower? A. Mean response before the program Mean response after the program C. Cannot be determined B. 13. Given the values, Is the result not significant? B. No A. Yes 14. What is the decision to be made? A. Accept Ho B. Reject Ho 15. What is the conclusion to the problem? A. There was no enough evidence to support the claim; hence, there was a change in attitude toward exercise. B. There was enough evidence to support the claim; hence, there was a change in attitude toward exercise. C. There was enough evidence to support the claim; hence, there was no change in attitude toward exercise. D. There was no enough evidence to support the claim; hence, there was no change in attitude toward exercise.
