Based on data collected by the U.S. General Social Survey, a
researcher examines the frequency with which adults responded to
two questions. The first asked people if they resided in the same
city or town now as when they were 16 years old
(Residence). The second asked if they found life generally
exciting, routine, or dull (Life). Using data from 2,791
people, the results are below.
Life is Generally:
Living in:
Exciting
Routine
Dull

Using the chi-square (χ2)
test for independence, examine whether the
feelings people have about life in general are related to living in
the same city or town as when a teen.
a. State the hypotheses (H0 and H1).

b. Find the critical value for α = .05, 1-tailed. (1

c. Calculate the test statistic (χ2), filling in
relevant portions of the table above as you go. (2
points)
d. Make a statistical decision and write a conclusion statement.
Remember to informally compare observed and expected values to
