Intelligence quotas on two different tests are normally distributed. Test A has a mean of 100 and a standard deviation of 18. Test B has a mean of 100 and a standard deviation of 16. Use z-scores to determine which person has the higher IQ: an individual who scores
133 on Test A or an individual who scores 120 on Test B. Which individual has the higher IQ?
A.
The individual who scores 120 on Test B.
B.
The individual who scores 133 on Test A.
C.
Both individuals have the same IQ.

5) Intelligence as measured by IQ tests is normally distributed with a mean 100 and standard deviation 15. Suppose groups of 10 people is selected at random. What percentage of these groups will have a mean IQ between 105 and 110?

Stanford–Binet IQ Test scores are normally distributed with a mean score of 100 and a standard deviation of 15. (10 points) Sketch the distribution of Stanford–Binet IQ test scores. Write the equation that gives the z score corresponding to a Stanford–Binet IQ test score. Sketch the distribution of such z scores. Find the probability that a randomly selected person has an IQ test score Over 145. Under 91.
iq scores are normally distributed with a mean of 100 and a standard deviation of 15. a person who's score is higher than 84% has iq of?
Background: IQ test scores based on the Wechsler Adult Intelligence Scale (WAIC) are approximately Normally distributed with a mean of 100 and a standard deviation of 15. Question: An adult whose IQ score is within the central 50% of all adult IQ scores is said to have "normal" or "average" intelligence. Therefore, an adult of normal intelligence would have an IQ score between what two values?
Suppose scores on an IQ test are normally distributed. If the test has a mean of 100 and a standard deviation of 10, what is the probability that a person who takes the test will score between 90 and 110?
A. Scores on the Wechsler Intelligence Scale for Children (WISC) are standardized to be normally distributed with a mean of 100 and standard deviation of 15. 1.What is the WISC score of a child who scored 2 standard deviations above the mean? 2. What is the WISC score of a child who scored half a standard deviation below the mean? 3. What is the WISC score for a child whose z score was 0? B. SAT-Math scores have a mean...
IV. Assume that IQ scores are normally distributed, with a mean of 100 and standard deviation of 15. What is the probability that a randomly selected person has an IQ score a greater than 120? b. less than 902 c. between 90 and 120? d. between 105 and 120?
Intelligence quotient (IQ) scores are often reported to be normally distributed with a mean of 100 and a standard deviation of 15. (a) If a random sample of 50 people is taken, what is the probability that their mean IQ score will be less than 95? (b) If a random sample of 50 people is taken, what is the probability that their mean IQ score will be more than 95? (c) If a random sample of 50 people is taken,...
