Solution: Depending on what your distribution represents, start by either writing the formula for the z-score of a population: z = x−μ σ z = x − μ σ. If you are using a calculator, make sure you put the numerator in parentheses to ensure it is evaluated first. Here, we round the answer to 2 decimal places. z = (169− 116) 12 z = ( 169 ...
