8.2b Standard Normal Distribution Tables (Example 3)

Example 3:
Find the value of k if
(a) P(Z > k) = 0.0480
(b) P(Z > k) = 0.8350

Solution:
(a)

From the standard normal distribution table, k = 1.665

 Z 6 5 (Subtract) 1.6 0.0485 5

(b)

From the standard normal distribution table,
k = –0.974 ← (Remember to put a negative sign at the value of k because it is on the left-hand side of the normal curve.)

 Z 7 4 (Subtract) 0.9 0.166 10
