Question

What is the probability that z > 0.82

What is the probability that z < -2.14?

0.0026 is the probability that z is below what value?

0.3446 is the probability that z is below what value?

Answer 1

Answer #1

These all needs to be done by using some statistics software or z-table.

Here are answers from statistics software:

P(z > 0.82) = 0.2061

P(z < -2.14) = 0.0162

z = -2.79 when area below of that z is 0.0026.

z = -0.4 when area below of that is 0.3446

Please comment if any doubt. Thank you.
