2)63 in
3)7853.98 mm (round as you want)
4)153.94 ft

Step-by-step explanation:
Z = (X-Mean)/SD
<span>z1 = (165 - 150)/15 = +1 </span>
<span>z2 = (135 - 150)/15 = - 1 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean +/- 1SD covers 68% of the values </span>
<span>100% - 68% = 32% </span>
<span>The remaining 32% is equally distributed below z = - 1 and z = +1 </span>
<span>32%/2 = 16%
</span>
<span>Therefore,
</span>
<span>a) Number of men weighing more than 165 pounds = 16% of 1000 = 160 </span>
<span>b) Number of men weighing less than 135 pounds = 16% of 1000 = 160</span>

Step-by-step explanation:
The slope intercept or y-intercept is where the line starts from the center. Since a point on the line starts at 0,-3, you pull the y out from the coordinate, because that is your answer. The line starts at -3.
