This is a statistics class for bio. Independent random samples of non-Hispanic Black and non-Hispanic White children (below age 18), all living below the poverty level, were assessed for a variety of health conditions, including asthma. Of the 150 Black children, 31 had asthma. Of the

200 White children, 24 had asthma.

1. Construct the appropriate 2 x 2 contingency table for these data.
2. The null hypothesis is that there is no difference between Black and White children who are living below the poverty level with respect to prevalence of asthma; the alternative hypothesis is that there is a difference. Perform the appropriate analysis using the p-value method at level =.05.
3. Interpret the result.
4. Estimate the odds ratio relating ethnicity (Black versus White) and asthma among children living below the poverty level, and then interpret it.
5. Is there evidence of a difference between Black and White children who are living below the poverty level with respect to prevalence of asthma?
