# Question: Find the probability that a piece of data picked at

Find the probability that a piece of data picked at random from a normal population will have a standard score (z) that lies to the left of the following z-values

a. z = 2.10

b. z = 1.20

c. z = 3.26

d. z = 0.71

a. z = 2.10

b. z = 1.20

c. z = 3.26

d. z = 0.71

Understanding the z notation, z(a), requires us to c. z(100 — 001) d. z (0.025) — z (0.975) know whether we have a z-score or an area.
