### Normal distribution: Finding the mean and standard deviation

In this tutorial you are shown how to calculate the mean and standard deviation from a normal distribution using the following example. 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
