The value 64 cm comes from a population with mean 50 cm
and standard deviation 5 cm.
---
z(64) = (64-50)/5 = 14/5 = 2.8
64 is 2.8 standard deviations above the mean of its population.
-----
The value 40 inches comes from a population with mean 30 inches and standard deviation 3 inches.
---
z(40)=(40-30)/3 = 3.3333...
40 is 3 1/3 standard deviations above the mean of its population

Calculate and compare their z-scores?
