Assume men h ve hip breadths that are normally distributed with a mean of 14.9 in. and a standard deviation of 1 in. Cumplete parts (a) through (c) below (a) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.8 in.

Answer 1

a)

for normal distribution z score =(X-μ)/σ
here mean=       μ=	14.9
std deviation   =σ=	1.0000

probability =

P(X>16.8)

=

P(Z>1.9)=

1-P(Z<1.9)=

1-0.9713=

0.0287
