Question

1. the area under the standard normal curve corresponding to z - scores below - 0.45 is (a) 0.3263 (b) 0.4713 (c) 0.5631 (d) 0.9542 (e) none of the above

Explanation:

Step1: Use z - table

We look up the z - score of - 0.45 in the standard normal distribution table (z - table). The z - table gives the cumulative probability (area under the curve to the left of the z - score).

Step2: Find the value

From the standard normal table, the area corresponding to z=-0.45 is 0.3264 (the closest value in the table). This value is very close to 0.3263.

Answer:

A. 0.3263
