researcher believes that table-top role playing games can change creative intelligence through problem solving. To test this, the researcher recruits 5 participants from a university who have never played a table-top role playing game before, and instructs them to play Dungeons and Dragons (D&D) weekly for two months. An experienced Game Master (GM) is recruited as a confederate for the participants. This confederate runs the campaign, and helps the participants understand the mechanics for the game. The participants are then tested using Sternberg’s test for creative intelligence (scores provided below.). Their data is compared to the population average of 100.5.

Please state the null and alternative hypotheses.
Using an alpha level of .05, please test the null hypothesis (what is the appropriate test, what is the critical
value?). Draw the rejection region.
