Uperture Science is testing how different Long Fall Boot prototypes affect “Subject Survival Probability.” To be thorough, GaldOS decides to test six different boot materials (Carbon, Gel-Infused, Titanium, Plastic, Moon Rock Composite, Neurotoxin-Resistant Ceramic) to see if any one is better than the others.GaldOS is going to do pairwise comparisons creating a confidence interval for for every combination pair.  That would be a total of 15 comparisons.  The confidence level is going to be 95% using the classic t-test method without accounting for the fact that there are multiple comparisons happening here. What is the EWER for this analysis?
