#### Answer

$62.4\leq h\leq 74.0$

#### Work Step by Step

$| \frac{h-68.2}{2.9}|\leq 2$
$-2\leq\frac{h-68.2}{2.9}\leq 2$
$-2*2.9\leq h-68.2\leq 2*2.9$
$-5.8\leq h-68.2\leq 5.8$
$62.4\leq h\leq 74.0$
This means that 95% of adult males fall within 2 inches of 68.2" in height (between 74 and 62.4 inches).
