19. Given a test statistic: Zc 2 and the known Z-values for common confidence intervals: 1.645, 1.96, and 2.576 for the 90%, 95% and 99 % confidence levels respectively. Can you reject the null hypothesis at the 95% confidence level? Be sure to define and discuss the test statistic and Z-values in your answer.
