Researchers at an epidemiology clinic are interested in the difference in the incidence of a number of severe adverse events that occur during a clinical trial between the control and treatment groups. Suppose the following table illustrates the incidences for the most common SAE reported in the population, severe nausea, reported over the course of the 10 year intervention. Total Participants Reporting Severe Nausea Total Participants Control 267 1789 Treatment 485 1024 A) Calculate the risk difference between the groups. B) Conduct a formal test to determine if there is a significant difference in the reports of severe nausea between the two groups. That is, What is your Z stat, p value, and interpret your results. Use an alpha level of 0.05.
