) The heights of women aged 20 to 29 are approximately Normal with mean 64 inches and standard deviation 2.7 inches. Men the same age have mean height 69.3 inches with standard deviation 2.8 inches. What are the zz-scores for a woman 4'8" tall and a man 5'9" tall? (You may round your answers to two decimal places)
Use the value of from Table A that comes closest to satisfying
the condition.
(a) Find the number zz such that the proportion of observations
that are less than zz in a standard Normal distribution is
0.3605.
(b) Find the number zz such that 90.82% of all observations from a
standard Normal distribution are greater than zz.
