people who recently ved parking tickets, 36 were older than 25 years and the other 14 were age 25 or younger. CO Is the age distribution for this sample significantly different from the distribution for the population of licensed drivers? Use a = .05. Research has demonstrated that people tend to be attracted to others who are similar to them- selves. One study demonstrated that individuals areThe Chi-Square Statistic: Test disproportionately more likely to marry those with surnames that begin with the same last letter as their own (Jones, Pelham, Carvallo, & Mirenberg, 2004). The researchers began by looking at marriage records and recording the surname for each groom and the maiden name of each bride. From these records it is possible to calculate the probability of randomly matching a bride and a groom whose last names begin with the same letter. Suppose that this probability is only 6.5%. Next, a sample of n = 200 married couples is selected and the number who shared the same last initial at the time they were married is counted. The resulting observed frequencies are as follows: Same Different Initial Initials iw ow 19 181 200 Do these date indicate that the number of couples with the same last initial is significantly different that would be expected if couples were matched ran- domly? Test with a = .05. 6. Suppose that the researcher from the previous problem repeated the study of married couples' initials using twice as many participants and obtaining
