Colen and coworkers investigated the relationship between birth weight and whether or not the mother had ever married. A sample of 1270 births was obtained from the National Longitudinal Survey of Youth (1979-2002). The data were cross-classiOed by whether or not the mother had every been married and whether or not the baby was under weight. The odds ratio of b = 0:45 was estimated; here this is the estimated ratio of the odds of low birth among mothers who had been married divided by the odds of low birth weight for mother who had never been married. The following 95% conOdence interval was computed for the odds ratio:
(0.24; 0.83) Suppose that we wish to test the null hypothesis that low birth weight is independent of marital status
at the = 0.05 level. What would be the result of the chi-square test for independence? A.) Fail to Reject H0
B.) Reject H0
C.) Can't tell from the above information.
