Carlos Says That He Thinks That While Humans Are More

Essay

Carlos says that he thinks that while humans are more right-handed than left-handed, the same probably isn't true for gorillas. Luis disagrees and says they probably are asymmetric too, but maybe they're more left-handed. Imagine they collect handedness data for 60 gorillas based on videos of the gorillas eating and 39 of the gorillas appear to be right-handed. Use the normal distribution to approximate the binomial distribution to answer this question. Does the data support Carlos or Luis? As part of your answer, present the test statistic and the P-value it corresponds to.
