Suggest mean iodine concentration in organic milk is less

Reference no: EM131432486

Public Health and Nutrition Iodine is an important nutrient for the human body, especially in hormone development. Milk is a natural source of iodine, and the mean amount in cow's milk is 88 mg/250ml. Milk from organic farms is reported to have a lower concentration of elements such as zinc, iodine, and selenium.

A random sample of 35 gallons of organic milk from Humboldt County, California, was obtained and the iodine concentration was measured in each. The sample mean was x^‾= 86.5. Assume σ = 3.4. Is there any evidence to suggest that the mean iodine concentration in organic milk is less than 88? Use a = 0.01.
