Question

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

the answer is
-1.75
1-P(z<1.75)
4%

Answer 1

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

Answer 2
