Scores on the Wechsler intelligence quotient (IQ) test for adults have a normal probability distribution with a mean score of 10

bixtya [17]

Answer:

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 $(\mu)$ = 100 and standard deviation $(\sigma)$ = 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: $P(X$

The probability can also be written as:

$P(X < x) =P(Z$

Thus,

$P(X$

Using the Normal probability table probability of Z = -1 is 0.1587

Thus, the required probability is 0.1587
