The quantity you want is the area under the standard normal curve (with mean 100 and std dev 15) between 110 and 120.

According to my TI-83 calculator,

normalcdf(110,120, 100, 15) = 0.16, or 16%.

Answer:

160 m

Step-by-step explanation:

For the 15-deg angle, h is the opposite leg.

The hypotenuse is 628 m.

The trigonometry ratio that relates the opposite leg and the hypotenuse is the sine.

sin A = opp/hyp

$\sin 15^\circ = \dfrac{h}{628~m}$

$h = 628~m \times \sin 15^\circ$

$h = 162.54~m$

Rounded to 2 significant figures:

h = 160 m
