Question

Find the endpoint(s) on a N(0, 1) density with the given property, Round to three decimal places.

The area to the right of the endpoint is about 0.85.
a) - 1.036
b) - 0.842
c) 1.036
d) 1.375

Answer 1

The endpoint with about 0.85 area to the right on a standard normal density curve is found to be -1.036.

Step-by-step explanation:

The question concerns finding the endpoint on a standard normal density curve, specifically for N(0, 1), the standard normal distribution. The goal is to identify the z-score where the area to the right of it is approximately 0.85. Using a standard normal distribution table, probability table, or calculator function such as invNorm in a TI-83/84 calculator, you can find that the z-score with an area of 0.85 to the right side corresponds to a z-score of about -1.036. Hence, the correct answer is a) -1.036 as this is consistent with the area provided.
