According to the US Census Bureau,4 about 27.5% of US adults over the age of 25 have a bachelor’s level (or higher) college degree. For random samples of n = 500 US adults over the age of 25, the sample proportions, p̂, with at least a bachelor’s degree follow a normal distribution with mean 0.275 and standard deviation 0.02. Draw a sketch of this normal distribution and label at least three points on the horizontal axis.
