A set of data items is normally distributed with a mean of 60 and a standard deviation of 8. Convert 36 to a z-score.
--------------
It's z-score is the distance a data point is from the mean
of its data set using the standard deviation as a unit for
measurement.
-------------
z(36) = (36-60)/8 = -24/8 = -3
That tells you 36 is 3 standard deviations to the left of the mean.
