Problem 6 in Chapter 17 cited a study showing that people tend to choose partners who are similar to themselves. Jones, Pelham, Carvallo, & Mirenberg, 650 CHAPTER 18 (2004) demonstrated that people have a tendency to select marriage partners with surnames that begin with the same last letter as their own. The probability of randomly matching two last names beginning with the same letter is only p  0.065 (6.5%). The researchers looked at marriage records and found that 38 out of 400 brides and grooms had surnames beginning with the same last letter. Is this significantly more than would be expected by chance? Use a two-tailed test with α = .05.
