12. In Problem 11, a researcher asked college students to evaluate three new cell phone designs. However, the researcher suspects that college students may have criteria that are different from those used by older adults. To test this hypothesis, the researcher repeats the study using a sample of n  60 older adults in addition to a sample of n  60 students. The distribution of preference is as follows:

Design 1 Design 2 Design 3 Student 27 20 13 60 Older Adult 21 34 5 60 48 54 18 Do the data indicate that the distribution of preferences for older adults is significantly different from the distribution for college students? Test with   .05.
