Are you going to be using a one- or two-tailed test? Explain the reason for your choice. Find the corresponding critical z-value for Type I error rate (alpha) of = 0.05. Calculate your observed z-statistic. Compare your observed z-statistic to the critical z-value. What do you conclude regarding the null hypothesis? Calculate and interpret the standardized effect size (Cohen's d). In everyday language, what do you conclude about your research
