Suppose that the heights of adult women in the United States are normally distributed with a mean of 63.5 inches and a standard deviation of 2.3inches.
--------------------------------
Jennifer is taller than 75% the population of U.S. women.
Find the z-value corresponding to the lower 75% of the population: z=0.6744897...
--------------------------------
How tall (in inches) is Jennifer?
Find the x-value corresponding to z=0.6744897..
0.6744897 = (x-63.5)/2.3
x-63.5 = 1.551326...
x = 65.05 inches (Jennifer's height)
-------------------------------
Carry your intermediate computations to at least four decimal places. Round your answer to at least one decimal place.
