In a survey, it was found that consuming fruit juices is not as healthy as consuming fruit. It is believed that fruit juices contain artificial flavors and preservatives (Source: http://www.fda.gov/food/guidanceregulation/guidancedocumentsregulatoryinformation/labelingnutrition/ucm064880.htm). Assume that in a survey to assess whether or not people believe fruit juices contain artificial flavor, 53% believed that fruit juices contain artificial flavors.In a random sample survey of 100, construct a 95% confidence interval for the population proportion who believe that fruit juices contain artificial flavors. Do the results indicate that the majority of the population believes that they contain artificial flavors?Now modify the sample from 100 to3,600, construct a 95% confidence interval for the population proportion that believes that fruit juices contain artificial flavors. What do the results indicate now?
