A recent survey showed that 83% of south Florida residents prepared ahead of time hurricane Michael by purchasing extra food, water, and gasoline. If researchers want to verify these results, what is the minimum number of south Florida residents want to verify these, what is the minimum number of south Florida that must be 95% confident that the estimate is within 7 percentage points of the true population percentage?
For Broward County, Florida, hurricane season is 24 weeks long. It is assumed that the time between hurricanes is exponentially distributed with a mean of 6 weeks.
