Question

find the area of the shaded region. the graph depicts the standard normal distribution with mean 0 and standard deviation 1. click to view page 1 of the table. click to view page 2 of the table. the area of the shaded region is . (round to four decimal places as needed.)

Explanation:

Step1: Use z - table lookup

We look up the z - value of 0.67 in the standard normal distribution table. The standard normal distribution table gives the cumulative probability from negative infinity to a given z - value.

Step2: Find the area

The area to the left of z = 0.67 in the standard normal distribution represents the shaded region. Looking up z = 0.67 in the standard - normal table, we find that the cumulative probability is 0.7486.

Answer:

0.7486
