Question

Does presentation methodology improve retention for remembered material? You know that the average number of concepts remembered from a lecture is 20. You present information using a song to a group of four participants. Here are their scores for the number of concepts they remember from a lecture:
20, 21, 18, 29

Please conduct all steps of hypothesis testing and evaluate using a one tailed test and alpha =.01. You must use all five steps in hypothesis testing:

1. Restate the question as a research hypothesis and a null hypothesis about the populations.
2. Determine the characteristics of the comparison distribution.
3. Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected.
4. Determine your sample’s score on the comparison distribution.
5. Decide whether to reject the null hypothesis.
