... average height is normally distributed with mean 68 inches with a standard deviation of 3 inches, but the weights are only known to be normally distributed. This means the errors in prediction with any regression line assumed will be normally distributed. Suppose that we take a representative sample ...

... The median is the middle number. To find the place of the middle number put the values in order and count how many values there are. Add 1 to that number and divide by 2. This will give you the place of the median. In the example above: 16 people climbed the mountain. 16 + 1 is 17. 17 ÷ 2 is 8½. The ...
