Probability = 0.1587
Step-by-step explanation:
The provided information is:
Let X be the scores of the IQ test for adults that is normally distributed with mean = 100 and standard deviation
= 15.
Also, US military has minimum IQ score of 85.
Thus, the probability that randomly selected adult does not meet US military enlistment standards is:
The probability can also be written as:
Thus,
Using the Normal probability table probability of Z = -1 is 0.1587
Thus, the required probability is 0.1587
