So in this spreadsheet, I've plotted normal distribution. You can change the assumptions that are in this kind of a green-blue color. So right now it's plotting it with a mean of 0 and a standard deviation of 4. And I just write the variance here just for your information. The variance is just the standard deviation squared. And so what happens when you change the mean? So if the mean goes from 0 to let's say it goes to 5.
