Z Test Statistic & p Value: With Work Shown

Play to Learn

Goal(s):  Gain experience with evaluating the null hypothesis, whether provided the Z test or the p-value.  Observe how the width of the Distribution of Sample Means decreases with an increase in sample size, affecting both the Z test and p value.

How: For each scenario presented, decide based upon the Z Test or p-value, whether the results are statistically significant (such that the null hypothesis should be rejected and the research hypothesis supported).  Make 30 quick decisions, with immediate feedback.  Site: P2L.io
