Question: Public Health and Nutrition High levels of the chemical dioxin, ingested through food and air, can cause diabetes, immune disorders, and cancer. The U.S. EPA has set a maximum acceptable level of dioxin in blood at 10 ppt (parts per trillion). Residents living near an old incinerator known to produce dioxin air pollution have complained of many health problems. A random sample of people living within a 10-mile radius of the facility was obtained, and the dioxin level (in ppt) in the blood of each was measured. Is there any evidence to suggest that the mean dioxin level in the blood of residents living near the incinerator is greater than 10 ppt? Assume σ = 2.66, use a = 0.05, and compute the p value.
