Question

1. Find the z-score z ∗ for each. (a) P(z < z∗ ) = 0.47 (b) P(z > z∗ ) = 0.82

Jon S. · Accepted Answer

a) Search for z-score associated with probability of 0.47 in standard normal probability table.

b) If P(z > z*) = 0.82, then P(z < z*) = 1 - 0.82 = 0.18. Search for z-score associated with 0.18 in standard normal probability table.
