The Correct Answer is D

The Cult of Statistical Significance: How the Standard Error Costs Us Jobs, Justice, and Lives (Economics, Cognition, and Society)Since the relative risk for the high risk group is less than one (0.8 ), that indicates that there really is a decreased risk for the supposed high risk group. Because a relative risk value of one indicates that there is no difference in risks for the two groups and because the value of one is within the 95 percent confidence interval, this indicates that the decreased risk is not statistically significant. In order for the decreased risk to be statistically significant, the entire 95 percent confidence interval would have to less than one.
