the distribution of heights of American women aged 18 to 24 is approximately normally distributed with mean 65.5 inche and standard deviation 2.5 inches. what is the probability that a randomly seleted woman is between 60 and 64 inches tall?

Use zscores and a ztable to determine your probability.
Formula:
z = (x  mean)/sd
Find both zvalues:
z = (60  65.5)/2.5
z = (64  65.5)/2.5
Once you calculate both zvalues, check a ztable for the probability between those two values.
I hope this will help.
