A population is normally distributed with mean μ = 100 and
standard deviation σ = 20. Find the probability that a value
randomly selected from this population will have a value between 90
and 130. (i.e., calculate P(90<X<130))

Suppose that a population is known to be normally distributed
with μ = 2,400 and σ = 220. If a random sample of size n = 8 is
selected, calculate the probability that the sample mean will
exceed 2,500.

distributed with an average life (μ) of 12 years and a population
standard deviation (σ) of 1.4 years.
What proportion of Hoover vacuum cleaners will last 14 years
or more?
2. Suppose the lifetimes of Hoover vacuum cleaners are
normally distributed with an average life (μ) of 12 years and a
population standard deviation (σ) of 1.4 years.
Calculate the 80th percentile.
3. Suppose the lifetimes of Hoover vacuum cleaners...

Suppose that a population is known to be normally distributed
with
μ =2,300 and σ=250. If a random sample of size
n =8 is selected, calculate the probability that the sample
mean will exceed
2,400.

If a population is distributed with a mean μ and a standard
deviation σ, then the distribution of sample means is
distributed
A) normally with mean μ and standard deviation σ.
B) normally with mean μ and standard deviation σ/√(n).
C) with mean μ and standard deviation σ.
D) with mean μ and standard deviation σ/√(n).

Suppose a college math scores are approximately normally
distributed with mean μ=70 and standard deviation σ=10.
a. What score should a student aim to receive to be in the 95th
percentile of the math scores?
b. You took a random sample of 25 students from this population.
What is the probability that the average score in the sample will
be equal to or greater than 75?

1. Assume that adults have IQ scores that are normally
distributed with a mean of μ=100 and a standard deviation σ=15.
Find the probability that a randomly selected adult has an IQ
less than 130.
2. Assume the readings on thermometers are normally distributed
with a mean of 0 °C and a standard deviation of 1.00 °C.
Find the probability P=(−1.95<z<1.95), where z is the
reading in degrees.

and standard...

The random variable X is normally distributed. Also, it is known
that P(X > 161) = 0.04. [You may find it useful to reference the
z table.]
a. Find the population mean μ if the population standard
deviation σ = 13. (Round "z" value to 3 decimal places and final
answer to 2 decimal places.)
b. Find the population mean μ if the population standard
deviation σ = 24. (Round "z" value to 3 decimal places and final
answer to...
