For each letter, represent in a normal curve.

student are shorter than 5 feet is obtained as-

(x < 5)=P (
0.196572

c). The required percentage of male/female
students are shorted than 6 feet is obtained

as-
~30. 237%

P (x < 6)=P ( <

The standard deviation of the distribution is
obtained as-
× E; (x – F)'
V
S tan dard deviation (o)=
=V x 0. 8213
