1. So now we have that our population parameters are about 13 for the mean and 4.8
2. for the standard deviation. And remember the units are average karma points per
3. post. Using these rounded values, let's draw our distribution. We're going to
4. say that it's normal so here's our theoretical probability density function. And
5. here where the mean, equals the median, equals the mode, we have 13. Let's say
6. here's one standard deviation above the mean, and here's standard deviation less
7. than the mean. And here's two standard deviations. If our standard deviation is
8. 4.8, then what should our values be here, here, here, and here?
