Question: Public Health and Nutrition Many remember actor Michael J. Fox as conservative Republican Alex Keaton on the TV show Family Ties. After more than 10 years, he returned to television during the Fall of 2013 as a news anchor diagnosed with Parkinson's disease. The show reflects much of his frustrating experience. Most cases of Parkinson's disease are linked to environmental or genetic factors. It has been reported that approximately 15% of people with Parkinson's disease have a family history of the disease. A random sample of 420 Parkinson's patients was obtained, and 78 had a family history of the disease. Is there any evidence to suggest that the proportion of Parkinson's patients with a family history of the disease is different from 0.15? Use a = 0.05.
