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).

Explanation:

Step1: Recall the standard - normal distribution property

The standard - normal distribution has a mean of 0 and a standard deviation of 1. We want to find $P(Z < 1.50)$.

Step2: Use the standard - normal table

Looking up the value of 1.50 in the standard - normal table (or using a calculator with a normal - distribution function), we find the cumulative probability.

Answer:

0.9332
