FRAME 53.

Since the normal curve is symmetric, we know that half of these areas will lie on either side of

the mean. The areas for the right side are shown in the diagram below:

The areas for the left side are exactly the same as for the right side.

QUESTION:

What percentage of the area under the curve lies between:

a. u - 1σ and u + 1σ

? ______

b. u - 2σ and u + 2σ ? ______

c. u - 3σ and u + 3σ

? ______

d. u - 1σ and

u

? ______

e. u and u + 1σ

? ______

f. u - 1σ and u + 2σ ? ______
