Question 698341
There is a useful rule in statistics called the 68-95-99.7 Rule. It says that, for normally distributed data, 68% of values lie between -1 and 1 standard deviation from the mean, 95% lie between -2 and 2 standard deviations from the mean, and 99.7% lie between -3 and 3 standard deviations from the mean.<br>

Using this rule, 68% of incomes lie between the mean +/- 1 standard deviation. Here, this is $52,000 +/- $1,000 = $51,000-$53,000.
