Question
Is the number of children that a college student cur- rently has independent of the type of college or univer- sity being attended? Suppose students were randomly selected from three types of colleges and universities and the data shown represent the results of a survey of those students. Use a chi-square test of independence of answer the question. Let a = .05.
Type of College or University Community Large Small College University College 0 25 178 31 1 49 141 12 Number of Children 2 31 L 3 or more 22Explanation / Answer
H0: the number of children that a college student cur- rently has independent of the type of college or univer- sity being attended
H1: the number of children that a college student cur- rently has not independent of the type of college or univer- sity being attended
Let the los be alpha = 0.05
The expected frequencies are
The chisquare contributions are
Critical X^2: 9.48772
P-Value: 0.9854
The P-value is 0.9854> alpha 0.05, so we accept H0
Thus, we conclude that the number of children that a college student cur- rently has independent of the type of college or univer- sity being attended
