How can you rewrite (z ≤ - 1.75) in order to find the answer?

the answer is

-1.75

1-P (z<1.75)

4%

Since the Normal Distribution is symmetrical:

P (z ≤ - 1.75)

P (z"1.75)

1 - P (z ≤ 1.75)

1 - 0.9599

0.04001 * 100

4.001 %

Almost 4%

Just find the probability of z ≤ 1.75 using the z-table,

Subtract that from 1
