The Stanford-Binet Intelligence Scale is an intelligence test, which, like many other IQ tests, is standardized in order to have a normal distribution with a mean of 100 and a standard deviation of 15 points.
As an early intervention effort, a school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.
Determine the margin of error, mm, of a 99% confidence interval for the mean IQ score of all students with the disorder. Assume that the standard deviation IQ score among the population of all students with the disorder is the same as the standard deviation of IQ score for the general population, σ=15σ=15 points.
Give your answer precise to at least two decimal places.

IQ scores (as measured by the Stanford-Binet intelligence test)
are normally distributed with a mean of 95 and a standard deviation
of 14. Find the approximate number of people in the United States
(assuming a total population of 280,000,000) with an IQ higher than
126. (Round your answer to the nearest hundred thousand.) How many
People?
Also please explain thoroughly and where the 0.5 and the other
decimal number come from. Thanks in advance!

Scores on the Stanford-Binet Intelligence Test (IQ) are
normally distributed with mean
µ = 100 and standard deviation σ
= 16.
If a random sample of 49 individuals are selected, calculate the
probability that the sample mean IQ is less than 96. (round your
answer to the nearest four decimal places)

Tests such as the Wechsler Intelligence scales and the
Stanford-Binet produce scores that are commonly called IQ scores.
These tests are considered reliable measures of general cognitive
ability. They have a mean of 100 and a standard deviation of 15.
The scores on IQ tests are normally distributed.
a. Draw the distribution of IQ scores. Label the mean and the IQ
scores which correspond to 1, 2, and 3 standard deviations from the
mean.
b. Calculate the z-scores for the...

The Stanford-Binet IQ test is nationally normed with a mean of
100 and a standard deviation of 15. A principal in an elementary
school believes that her students have above-average intelligence
and wants verification of her belief. She randomly selects 20
students and checks the student files. You will use a z-test to
determine whether the students in this school have above-average
intelligence and will summarize your findings in a report.
IQ scores for 20 students are found in the...

Question 2: (Marks: 2)
Intelligence quotients (IQs) on the Stanford-Binet intelligence
test are normally distributed with a mean of 100 and a standard

An intelligence quotient, or IQ, is a measurement of
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.
a. Draw 1000 samples of size n=9 from the distribution of IQ.
Calculate the sample mean of all 1000 samples.
b. Draw the histogram for all sample means in (a). What is the
shape of the sample means?
c....
