Example: The National Health Interview Survey for 2011-2014 estimates that 37%   of 18-24 year olds are not meeting the Physical Activity Guidelines for Americans. These guidelines include recommendations for both aerobic and muscle-building exercise. Suppose that we survey 30 randomly selected students in this age category and find that 45% are meeting the Physical Activity Guidelines for Americans. Find the 95% confidence interval and interpret it.   a. Verify that the conditions for the use of the normal model are met based on the NHIS b.Calculate the standard error based on the NHIS c.Find the 95% confidence interval and represent it as a line d.Interpret the interval
