According to a human modeling project, the distribution of foot lengths of women is approximately normal with a mean of 23.4 centimeters and a standard deviation of 1.3 centimeters. in the united states, a woman's shoe size of 6 fits feet that are 22.4 centimeters long. what percentage of women in the united states will wear a size 6 or smaller?
Answers: 2
and 
.![P(x\leq22.4)=P(z\leq\dfrac{22.4-23.4}{1.3})\ \ [\because z=\dfrac{x-\mu}{\sigma}]\\\\\approx P(z\leq-0.77)\\\\=1-P(z\leq0.77)\\\\=1-0.77935=0.2206499\approx0.2206=22.06\%](/tpl/images/0332/3156/483a7.png)
