Question 558:



No answer provided yet.

To find the area between to points on the normal curve we need to find the area for the larger value and subtract out the area for the smaller value. We can either use a table of normal probabilities or the z-score to percentile calculator . We'll want to use the 1-sided area.


For the larger z-value of 1.88 we get an area of 96.99% and for the smaller z-score of .73 we get 76.73%. So 96.99-76.73 = 20.26% of the area. Expressed as a probability it's just .2026 probability that Z will fall between .73 and 1.88.
