A recent GSS was used to cross-tabulate income (<$15 thousand, $15–25 thousand, $25–40 thousand, >$40 thousand) in dollars with job satisfaction (very dissatisfied, little dissatisfied, moderately satisfied, very satisfied) for 96 subjects.
a. For these data, X2 = 6.0. What is its df value, and what is its approximate sampling distribution, if H0 is true?
b. For this test, the P-value is 0.74. Interpret in the context of these variables.
c. What decision would you make with a 0.05 significance level? Can you accept H0 and conclude that job satisfaction is independent of income?
