Find critical value ti 84.

Thus, α/2 = 0.1/2 = 0.05. To find the corresponding z critical value, we would simply look for 0.05 in a z table: Notice that the exact value of 0.05 doesn’t appear in the table, but it would be directly between the values .0505 and .0495. The corresponding z critical values on the outside of the table are -1.64 and -1.65.This calculator is intended to replace the use of a Z value table while providing access to a wider range of possible values for you to work with.
