Question 5 1 pts 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? 68% 95% 32% 5% 16% 2.5%

Scores on the Wechsler intelligence quotient (IQ) test for adults have normal probability distribution with a mean score of 100 and a standard deviation of 15 points. The US military has a minimum enlistment 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 probability that a randomly selected adult does not meet Us military enlistment standards?

Assume that adults have IQ scores that are normally distributed with a mean of 100 and a standard deviation of 15 (as on the Wechsler test). For a randomly selected adult, find the indicated probability or IQ score. Round IQ scores to the nearest whole number. (Hint: Draw a graph in each case.) Find the probability of an IQ less than 85.

The Intelligence Quotient (IQ) test scores for adults are normally distributed with a mean of 100 and a standard deviation of 15. What is the probability we could select a sample of 9 adults and find the mean of this sample is less than 98? 1) .725 2) 0.345 3) 0.345 4) .276
