In the United States, the prevalence of obesity in children is estimated to be around 18.5%.

In 2008, the CDC performed a study to determine if neighborhood type was associated with childhood obesity. The investigators decided to sample 50 children with obesity and 80 children without obesity and then asked whether they lived in a rural or urban neighborhood. The results are summarized in the following table:

1. Provide an estimate of the population odds ratio of obesity for rural vs. urban neighborhoods.

Round your final answer to two decimal places. Include a leading zero if appropriate (e.g 0.XX).

2. Fill in the blanks. For the first blank, round your final answer to one decimal place and do not include the % symbol, e.g. XX.X. For the second blank, enter "higher" or "lower", please be careful to avoid typos.

The odds of obesity for those living in rural neighborhoods is ------ % ---------- than the odds of obesity for those living in urban neighborhoods.

3. Compute a 95% confidence interval for the odds ratio of obesity for rural vs. urban neighborhoods.

Round your final answer to two decimal places. Include a leading zero if appropriate (e.g 0.XX).
