1. The document reports on various statistical analyses conducted on data related to height, weight, smoking status, and fetal outcomes. Hypothesis tests were conducted to compare means across groups. 2. Null hypotheses of equal means could not be rejected for tests comparing height of men and women, weight change before and after surgery, and smoking vs non-smoking status. The null hypothesis was rejected for differences in fetal outcomes between groups. 3. ANOVA tests found a significant effect of group on fetal outcomes.
