In Data 2.1 on page 46, we introduce a study in which people were asked whether they agreed or disagreed with the statement that there is only one true love for each person. Is the level of a person€™s education related to the answer given, and if so, how? Table 2.8 gives a two-way table showing the results for these two variables. A person€™s education is categorized as HS (high school degree or less), Some (some college), or College (college graduate or higher).

Table 2.8

(a) Create a new two-way table with row and column totals added.
(b) Find the percent who agree that there is only one true love, for each education level. Does there seem to be an association between education level and agreement with the statement? If so, in what direction?
(c) What percent of people participating in the survey have a college degree or higher?
(d) What percent of the people who disagree with the statement have a high school degree or less?

Data 2.1 on page 46

A nationwide US telephone survey conducted by the Pew Foundation in October 2010 asked 2625 adults ages 18 and older €˜€˜Some people say there is only one true love for each person. Do you agree or disagree?€ In addition to finding out the proportion who agree with the statement, the Pew Foundation also wanted to find out if the proportion who agree is different between males and females, and whether the proportion who agree is different based on level of education (no college, some college, or college degree). The survey participants were selected randomly, by landlines and cell phones.
