# Question: We are often interested in finding the value of z

We are often interested in finding the value of z that bounds a given area in the left-hand tail of the normal distribution, as shown in the accompanying figure. The notation z(a) represents the value of z such that P(z > z(a)) = a.

Find the following:

a. z(0.98)

b. z(0.80)

c. z(0.70)

Find the following:

a. z(0.98)

b. z(0.80)

c. z(0.70)

Use Table 4A, Appendix B, and the symmetry property of normal distributions to find the following values of z. a. z(0.05) b. z(0.01) c. z(0.025) d. z(0.975) e. z(0.98) a.
