Suppose pairs of fraternal twins are examined and the handedness of each twin is determined: assume that all the twins are brother-sister pairs. Suppose data are collected for 1,000 twin pairs, with the results shown in the following table. State whether each of the following statements is true or false.
(a) Most of the brothers have the same handedness as their sisters.
(b) Most of the sisters have the same handedness as their brothers.
