1. In a study of fraternal twins of different genders, researchers measured the heights of each twin. The data show that for each matched pair, the height of the male is greater than the height of his twin sister. What is the value of T?
2. Listed below are the genders of the first 25 subjects listed in Data Set 3 in Appendix B. Use that sequence to identify the values of n1, n2, and G that would be used in the runs test for randomness. M M M M M M M M M M M M M M M M M M F F M F M M M
3. A New York Times article about the calculation of decimal places of noted that "mathematicians are pretty sure that the digits of are indistinguishable from any random sequence." Given below are the first 30 decimal places of π. Test for randomness of odd (O) and even (E) digits. 1 4 1 5 9 2 6 5 3 5 8 9 7 9 3 2 3 8 4 6 2 6 4 3 3 8 3 2 7 9
