Expert Solution
IQ refers to mental age divided by chronological age, multipled by 100.
IQ=MA/CA×100
•William stern, a German psychologists, devised the concept of intelligence quotient.
• when MA=CA,IA=100
• If MA>CA, IQ>100
• If MA
• People with an IQ scores in the range of 90- 110 have normal intelligence.
• People with an IQ below 70 are suspected to have mental retardation.
• People with an IQ above 130 are considered to have exceptional talents.
IQ refers to mental age divided by chronological age, and multiplied by 100.

intelligence derived from a standardized test such as the Stanford
Binet IQ test. Scores on the test are normally distribution with a
mean score of 100 and a standard deviation of 15.

Part 1. The distribution of IQ (Intelligence Quotient) is
approximately normal in shape with a mean of 100 and a standard
deviation of 17.
According to the standard deviation rule, only
% of people have an IQ over 117.

(15 pts) A person’s Intelligence Quotient (IQ) is determined via
a series of test questions. The IQ score itself is designed to be
approximately normally distributed with a mean value of 100 and a
standard deviation of 15. In a sample of 20 students with
behavioral problems, a school administrator observes an average IQ
of 102.7. The administrator believes that students with behavioral
issues have a different cognition from their peers, and thus a
different average IQ. State the appropriate...
