The average height of flowering cherry trees in a nursery is 10.5 feet. If the heights are normally distributed with a standard deviation of 1.5, find the probability that a tree is less than 12.5 feet tall.
\n" ); document.write( "z(12.5) = (12.5-10.5)/1.5 = 2/1.5 = 4/3
\n" ); document.write( "------
\n" ); document.write( "P(x < 12.5) = p(z < 4/3) = normalcdf(-100, 4/3) = 0.9088
\n" ); document.write( "------------
