Normal distribution Calculator
Calculates the probability density function and lower and upper cumulative distribution functions of the normal distribution. | ||
| The default value μ and σ shows the standard normal distribution. |

- Purpose of use
- Checking some double-double precision (about 32 decimals) fast code for bugs, sometimes in extreme areas for ratio of cdf to pdf (Mills Ratio). Very impressed to find that you do up to 50 decimals AND report extreme range where exponent can be essentially -infinity, apparently, most do not do that, so I could ask my extreme questions about the ratio, was expecting to have to do my own verification some other way. Thanks!

- In a test in math, a class of 50 students obtained scores which are normally distributed with mean of 30 and whose SD is 5. How many students obtained scores lower that 25?
