In a recent study, authors were interested in the relationship between exposure to pesticides and incidents of ADHD. They measured levels of urinary dialkyl phosphate (DAP, a common pesticide) concentrations in a group of 1139 randomly selected U.S. children to determine ADHD diagnostic status (Yes/No). The subjects were divided into two groups based on high or low pesticide concentrations, and researchers compared the proportion with ADHD in each group. Is the proportion of children with higher exposureto pesticides more likely to develop ADHD (attention-deficit / hyperactivity disorder) than the proportion of children with low exposure to pesticides? What are the null and alternative hypotheses? Use the STATKEY output to answer the following: What is the sample statistic? Use proper notation with your value. What is the p-value? Write a general conclusion about your hypothesis test.
