The average height of flowering cherry trees in a certain nursery is 9.5 feet. If the heights are normally distributed with a standard deviation of 1.3 feet, find the probability that a tree is less than 11.5 feet tall.
--------------
z(11.5) = (11.5-9.5)/1.3 = 1.5385
----
P(x < 11.5) = P(z < 1.5385) = 0.9380
