Question

For a standard normal distribution, given: p(z < c) = approximately .98. answer as a whole number find c. c = _______

Answer 1

To find c in a standard normal distribution given a probability, we need to find the z-score that corresponds to that probability. Using a calculator or a standard normal probability table, we can find the z-score. In this case, the z-score is approximately 2.326, so c = 2.326.

Step-by-step explanation:

To find c, we need to find the z-score that corresponds to the area of approximately 0.98. Given that this is a standard normal distribution, we can use a calculator or a standard normal probability table to find the z-score. Using the calculator command invNorm(0.98,0,1) or referring to the table, we find that the z-score is approximately 2.326. Therefore, c = 2.326.
