Play to Learn

Goal(s): Gain expertise with hypothesis testing (comparing the p-value with the alpha level) for t>span class="C9DxTc "> test.  Notice the possibility of taking sample size into consideration, such that for a sample size of 30 or more, a Z test might be used even when the population standard deviation and distribution shape are unknown; consult with your instructor regarding best practices.  Recognize that if the result is considered "statistically significant," then the null hypothesis is rejected. 

How: For each scenario presented, compare the p-value with the alpha level, and decide whether to reject the null hypothesis.  Make 30 quick decisions, with immediate feedback.
