Question

Bees live in hives. each has a "home" hive. the distribution of distances bees who live in a given hive are away from "home" (in feet, at 2pm each day) is approximately normal and is given below

0.03 20 70 The percent of bees that are between 31 and 55 feet away from the hive is equivalent to: PA <Z<B). A= and B = (Be sure to put answers in decimalized form.)

Answer 1

Hello

YOUR REQUIRED ANSWERS ARE : A = -0.75, B = 1.25

From the given diagram, it is clearly visible that:

Mean = 40

S.D. = 12

Hence,

For A (i.e. 31)

$\frac{X-\mu}{\sigma}=\frac{31-40}{12} =-0.75$

For B (i.e. 55)

$\frac{X-\mu}{\sigma}=\frac{55-40}{12}=1.25$

Thanks!
