Question

For a standard normal distribution, determine the following probabilities. a) P(z>1.43)

Answer 1

To find P(z>1.43) for a standard normal distribution, determine the area to the right of 1.43 on the standard normal distribution curve. The probability is approximately 0.0764 or 7.64%.

Step-by-step explanation:

To determine the probability P(z>1.43) for a standard normal distribution, we need to find the area to the right of 1.43 on the standard normal distribution curve. Using a calculator or a z-table, we find that the area to the left of 1.43 is approximately 0.9236. Subtracting this value from 1 gives us the area to the right, which is approximately 0.0764. Therefore, P(z>1.43) = 0.0764 or 7.64%.
