![P(X 65) = P[\frac{X - \mu }{ \sigma_{\= x} } \frac{65 - 64.4 }{ \sigma_{\= x} } ]](/tpl/images/0725/7050/ef548.png)
is the standard error of mean which is evaluated as 
![P(X 65) = P[Z \frac{65 - 64.4 }{0.342 } ]](/tpl/images/0725/7050/0da48.png)
![P(X 65) = P[Z 1.754 ]](/tpl/images/0725/7050/a7d4b.png)
![P(X 65) = P[Z 1.754 ] = 0.039715](/tpl/images/0725/7050/e64f1.png)
