Help me please.

Luke Skywalker's height is 68 inches. The mean height for all Jedi is 66.5 inches and the standard deviation of the Jedi heights is 2.4 inches. What is the z score for Luke Skywalker's height?
Round to the nearest thousandth

Answer 1

The z-score is computed as follows.


`z=(x-\mu )/(\sigma )=(68-66.5)/(2.4)=0.625`.

The z-score is 0.625.
