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. Each of the following expressions uses the z notation in a variety of ways, some typical and some not so typical. Find the value asked for in each of the following, and then with the aid of a diagram explain what your answer represents.
a. z(0.08)
b. the area between z(0.98) and z(0.02)
c. z(1.00 _ 0.01)
d. z(0.025) _ z(0.975)
