Question 14

The way to interpret a confidence interval is as follows: If you repeated your survey multiple times (literally,thousands of times),and plotted your p,or percentage,found for each on a frequency distribution,it would look like a bell-shaped curve,and 95% of your percentages would fall in the confidence interval defined by the population percentage ±1.96 times the standard error of the percentage.
