Question 446665
A random sample of 100 adult workers, 60 men and 40 women, is selected in a large Midwestern city. Of the group, 42 men and 17 women are union members. Does union membership differ on the basis of gender? State the independent and dependent variables.
----------------------------
.................union...........non-union
men...............42................58........100
women.............17................83........100

============================
Ho: row and column factors are independent
Ha: they are dependent
-------------
I ran a Chi-Sq test on the data and got the following:
test statistic: Chi-Sq = 15.026
p-value: 0.00010605
=======================
Conclusion: Since the p-value is less than 5%, reject Ho.
the test result supports the conclusion there is a relation
of union membership to gender.
