4. Folwell and others (1997) interviewed a group of adults, aged 54 and older, about their relationships with their siblings. One question they asked was whether there had been a change in emotional closeness over the years. They found that 43 of the respondents “perceived changes of emotional closeness in their sibling relationships . . . [and] 14 did not report a change in closeness in their sibling relationships” (p. 846). They also tested whether this difference was greater than you would expect by chance (which would be a 50-50 split).
“A chi-square analysis revealed that respondents perceive changes in closeness in their sibling relationships 12 = 14.75, df = 1,  = .052” (p. 846).

(a) Figure the chi-square yourself (your results should be the same, within rounding error).

(b) Explain this result to a person who has never had a course in statistics.
