Quizplus · Accepted Answer

To find the population standard deviation, first calculate the mean of the data, then use the formula for the standard deviation, which involves squaring the difference between each data point and the mean, summing those values, dividing by the number of data points (since this is a population), and finally taking the square root. The correct calculation results in a standard deviation of approximately 7.7 years.
