Question 13 1 pts Scores on the Wechsler intelligence quotient (IQ) test are normally distributed 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. There have been two experiments with lowering this to 80 but in both cases these recruits could not master soldiering well enough to justify the costs. Based on IQ scores only, what percentage of the population does not meet US military enlistment standards? Ο 32% Ο 2.5% Ο 16% Ο 95% Ο 5% Ο 68% Question 14 nts

Step 1
The US military has a minimum enlistment standard of 85. We want to find the percentage of the population that does not meet this standard, i.e., the percentage of people with an IQ score less than 85. Show more…

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?

The intelligence quotient (IQ) score, as measured by the Stanford-Binet IQ test, is normally distributed in a certain population of children. The mean IQ score is 100 points, and the standard deviation is 16 points. What percentage of children in the population have IQ scores (a) 116 or more? (b) 84 or less? (c) between 84 and $116 ?$ (d) between 84 and $148 ?$ (e) between 116 and $148 ?$

Practice 2) Many researchers are interested in studying intelligence in many groups and populations, with a popular measure of intelligence being the IQ test. In the general healthy population, scores on an IQ test are normally distributed with 100 ± 15 (μ ± σ). Based on this distribution of IQ scores, what is the minimum score required on this test to have an intelligence score in the top 10% of scores in this distribution? 5. Let us use the same IQ data for intelligence from Practice 2, with a distribution of 100 ± 15 (M ± SD). Based on this distribution of IQ scores, what is the cutoff score for the bottom 25% of scores in this distribution?
