Heights of WOMEN in the U.S. are normally distributed.   Recent information shows:    Adult women height:      µ = 63.8 inches with σ = 2.8 inches.     From the given frequency distribution, we see that _____ of the 52 women in our RCCC sample were between 62 and 69 inches tall, which would be approximately _____ % (0 decimal places). This is __________ percentage points _______________ (above or below) that of the U.S. population. (Note: Include 62 and 69 inches.)
