Above I have created a graph of the variable "Average Estimated Total Submitted Charges."

The mean for this variable = $24,300

The standard deviation = $23,832

1. Looking at the figure above, what percentage of Submitted Charges would you estimate fall below $25,000?

2. What percentage of Submitted Charges actually fall below $25,000?

3. If our sample represented a perfect normal distribution, what would we expect the percentage of scores that fall below $25,000 to be?
