A company makes ball bearings whose diameters are normally distributed. When using the z-value to find a probability on the z-table, what does that probability mean?

• It is the probability that a random ball bearing will have a diameter that is equal to the diameter used to calculate the z-value.

• It is the probability that a random ball bearing will have a diameter that is greater than the diameter used to calculate the z-value.

• It is the probability that a random ball bearing will have a diameter that is greater than or equal to the diameter used to calculate the z-value.

• It is the probability that a random ball bearing will have a diameter that is less than or equal to the diameter used to calculate the z-value.
