Assume that adults have IQ scores that are normally distributed
with a mean of 100 and a standard deviation of 15 (as on the
Wechsler test). Find the IQ score separating the bottom 40% from
the top 60%.

A) 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 90
and 120. (Provide graphing calculator sequence)
B) Assume that adults have IQ scores that are normally
distributed with a mean of 100 and a standard of 15. Find P3D,
which is the IQ score separating the bottom 30% from the top 70%.

with a mean 105 and standard deviation of 20. a. Find the
probability that a randomly selected adult has an IQ less than 120.
b. Find P90 , which is the IQ score separating the bottom 90% from
the top 10%. show work

1) Find the area of the shaded region. The graph to the right
depicts IQ scores of adults, and those scores are normally
distributed with a mean of 100 and a standard deviation of 15.
x=90
The area of the shaded region is __. (Round to four decimal
places as needed.)
2) Find the area of the shaded region. The graph to the right
depicts IQ scores of adults, and those scores are normally
distributed with a mean of 100...

Assume that adults have IQ scores that are normally distributed
with a mean of 96.3 and a standard deviation 23.1 Find the first
quartile , which is the IQ score separating the bottom 25% from
the top 75%. (Hint: Draw a graph.)

Assume that adults have IQ scores that are normally distributed
with a mean of 101 and a standard deviation 24. Find the first
quartile Upper Q 1, which is the IQ score separating the bottom
25% from the top 75%.

1. Assume that a randomly selected subject is given a bone
density test. Those test scores are normally distributed with a
mean of 0 and a standard deviation of 1. Draw a graph and find the
bone density test scores that can be used as cutoff values
separating the lowest 6% and highest 6%, indicating levels that
are too low or too high, respectively.
2. Assume that the readings on the thermometers are normally
distributed with a mean of 0°...

c) Find the IQ score for the top 5%

Assume that adults have IQ scores that are normally distributed
with a mean of 96.2 and a standard deviation 19.2. Find the first
quartile Upper Q 1, which is the IQ score separating the bottom
25% from the top 75%. (Hint: Draw a graph.)

Assume that adults have IQ scores that are normally distributed
with a mean of 101.2 and a standard deviation 23.6 Find the first
