Normal Distribution
Finding the mean µ and standard deviation σ
In this tutorial I show you through an example how to calculate the mean and standard deviation of a normal distribution.
A high jumper knows from experience that she can clear a height of at least 1.78m once in 5 attempts. She also knows that she can clear a height of at least 1.65m on 7 out of 10 attempts.
Find to 3 dp the mean and standard deviation of the heights the jumper can reach
