Pls help I need this so bad Height has an approximately bell-shaped distribution. For a sample of heights of college students collected, the males had x=73 s=3 and the females had x=67 and s=3
Use this information to answer parts a and b
Approximately 68% of the observations fall within the interval:

139.2 cm^2

Step-by-step explanation:

Here we can see that there are 3 rectangles and since we're finding a lateral surface area we need to exclude A rectangle

Area of rectangle: LW

So area of two rectangles 2(LW)

2(9*6)

2*54=108

Area of triangles: (BH)/2

Area of two triangles

2(BH)/2

(the two twos cancel each other out)

So 6*5.2=31.2

Lets add up the numbers:

108+31.2=139.2
