Question

find the area under the standard normal distribution curve to the right of ( z = 0.40 ). use the standard normal distribution table and enter the answer to 4 decimal places. the area to the right of the ( z ) value is

Explanation:

Step1: Find the cumulative area for \(z = 0.40\)

From the standard normal distribution table, for \(z=0.40\), the cumulative area (area to the left of \(z = 0.40\)) is \(0.6554\).

Step2: Calculate the area to the right

The total area under the standard - normal curve is \(1\). The area to the right of \(z\) is \(A=1-\text{cumulative area for }z\). So, \(A = 1 - 0.6554=0.3446\).

Answer:

0.3446
