Question

Assume that adults have IQ scores that are normally distributed with a mean of 104.1 and a standard deviation of 23.6 Find the probability that a randomly selected adult has an IQ greater than 144.3

Answer #1

Assume that adults have IQ scores that are normally distributed
with a mean of 103.3 and a standard deviation of 16.2. Find the
probability that a randomly selected adult has an IQ greater than
127.4. (Hint: Draw a graph.) The probability that a randomly
selected adult from this group has an IQ greater than 127.4 is

Assume that adults have IQ scores that are normally distributed
with a mean of 102.9 and a standard deviation of 15.1 Find the
probability that a randomly selected adult has an IQ greater than
119.8

Assume that adults have IQ scores that are normally distributed
with a mean of 99.9 and a standard deviation of 15.5. Find the
probability that a randomly selected adult has an IQ greater than
125.3. (Hint: Draw a graph.)
The probability that a randomly selected adult from this group has
an IQ greater than 125.3 is
nothing.
(Round to four decimal places as needed.)

Assume that adults have IQ scores taht are normally distributed
with a mean of 96.2 standard deviation of 22.1. Find the
probability that a randomly selected adult has a IQ greater than
131.8

Assume that adults have IQ scores that are normally distributed
with a mean of 101.9 and a standard deviation of 23.9.
Find the probability that a randomly selected adult has an IQ
greater than 149.6
(Hint: Draw a graph.) (Round to four decimal places as
needed.)

Assume that adults have IQ scores that are normally distributed
with a mean of 100 and a standard deviation of 15. For a randomly
selected adult, find the probability. Round scores to nearest whole
number.
1.) Prob. of IQ less than 85
2.)Prob. of IQ greater than 70
3.) Prob. of randomly selected adult having IQ between 90 and
110.

Assume that adults have IQ scores that are normally distributed
with a mean of 200 and a standard deviation of 20. Find the
probability that a randomly selected adult has an IQ between 150
and 175.

Assume that adults have IQ scores that are normally distributed
with a mean of 100 and a standard deviation of 15. Find the
probability that a randomly selected adult has an IQ between 84 and
116.

Assume that adults have IQ scores that are normally distributed
with a mean of mu equals 100 and a standard deviation sigma equals
20. Find the probability that a randomly selected adult has an IQ
between 85 and 115. The probability that a randomly selected adult
has an IQ between 85 and 115 is:

Assume that adults have IQ scores that are normally dostributed
with a mean of u=97.4 and a standard deviation of o=23.8. Find the
probability that a randomly selected adult has an IQ less than
132.7. The probability that a randomly selected adult has an IQ
greater than 132.7 is ?
