Question 3(5 points)

A study by Southpaw University claims that left-handed people are more inclined to have increased intelligence levels than their right-handed counterparts.In an attempt to dispute this claim a researcher sampled individuals who have I.Q. scores exceeding 140 (the level which is commonly accepted to classify someone as a "genius") and recorded their dominant hand.10% of the world is left-handed.Based on the sample below, at a 1% level of significance, is there evidence that a higher proportion of geniuses are left-handed than the 10% seen in the world's general population.
