Question

A study of zinc-deficient mothers was conducted to determine effects on zinc supplementation
during pregnancy. Statistics of sample data are listed in Table 1. The weights were measured in
grams. Using a 0.05 significance level, is there sufficient evidence to support the claim that the
variation of birth weights for the placebo population is less than the variation for the population
treated with zinc supplements?

zinc supplement group	placebo group
n1=10	n2=15
mean 1=3214	mean 2=3088
s1=669	s2=728

Individual actions can play a large role in the overall health of our planet. A researcher interested in evaluating environment friendly behaviors evaluated how often people recycle (per month) based on whether they have an overall optimistic or an overall pessimistic attitude toward eco-friendly behaviors. The results from this hypothetical study are given in the table. Test whether or not recycling behaviors differed between groups using a .05 level of significance.
