Mean height of men, mean 68 inches and a standard deviation of 2.5 inches.
What is the probability of a man selected at random will have a hight above 72 inches?
A sample of 49 meant, what is the probaility that the mean hight is greater than 67 inches (using standard score table)?

By standard score table, you mean the Normal Distribution?

If so, first define your variable, that is the height.

Let X be the height of a man.



Then,

Find the z-score and look up your table for the corresponding probability. Make a sketch if needed to confirm your answer.
