2.Suppose that a recent study found that farmers exposed to heavy amounts of Roundup (a chemical weed killer) were 40% more likely to contract lymphoma than were those not exposed. Suppose that this difference was found to be statistically significant. What does this mean? Select one: a. Being statistically significant means that this observed difference is very likely: it occurs almost at least 95% of the time. b. Being statistically significant means it is sufficient to conclude that roundup is the cause for the lymphoma increase. c. Being statistically sigificant means that this difference is important. d. Being statistically significant means it is very unlikely if due entirely to chance
