Scores on the Wechsler intelligence quotient (IQ) test for adults have a normal probability distribution with a mean score of 100 and a standard deviation of 15 points. The US military has minimum enlistment standards at about an IQ score of 85. Based on IQ scores only, what is the probability that a randomly selected adult does not meet US military enlistment standards

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

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
