Question

answer the following. (a) the standard normal curve is graphed below. shade the region under the standard normal curve to the left of z = 1.50. (b) use this table or the aleks calculator to find the area under the standard normal curve to the left of z = 1.50. give your answer to four decimal places (for example, 0.1234). 0.9332

Explanation:

Step1: Understand z - table usage

The standard normal distribution table gives the cumulative probability (area under the curve to the left of a given z - score).

Step2: Locate z - score in table

For \(z = 1.50\), we look up the value in the standard normal distribution table. The table is organized such that the first digit and first decimal of the z - score are in the left - most column and the second decimal is in the top - most row. When we find the intersection of the row for \(1.5\) and the column for \(0.00\), we get the area.

Answer:

0.9332
