- Please solvearrow_forwardA personality psychologist is interested if being a snob is heritable. To answer this question a personality psychologist recruits a huge sample of 2,593 identical twins and found that identical twins were similar in how snobby they were with an effect size of r=0.6. They also recruit a huge sample of 1845 fraternal twins and found that fraternal twins were also similar in how snobby they were with an effect size of r=0.4. Calculate the heritability coefficient for being a snob.arrow_forwardLooking at hairline (widow's peak = H) and ear shape (ear lobes = E)...
