Answer #1

The distribution of weights of MP3 players is normally
distributed with a mean of 6 ounces and a standard deviation of 2.5
ounces. What is the probability that a randomly chosen MP3 player
has a weight of less than 4 ounces? Round to four decimal places.
Put a zero in front of the decimal point.

Assume that the distribution of the weights for a brand of mints
is normal with mean 21grams and standard deviation 0.5 grams. Let X
be the weight of a randomly chosen mint from this brand.
a. Find the probability that a randomly chosen mint from this
brand weighs at least 20 grams.
b. If a mint has a weight more than 20% of all the mints in this
brand. Find the weight of this mint.
c. If a SRS of...

Birth weights in the United States have a distribution that is
approximately normal with a mean of 3396 g and a standard deviation
of 576 g. Apply Table A-2 or statistics technology you can use to
answer the following questions:
(a) One definition of a premature baby is the the birth weight
is below 2500 g. If a baby is randomly selected, find the
probability of a birth weight below 2500 g.
(b) Another definition of a premature baby is...

The weights of pennies minted after 1982 are Normally
distributed with mean 2.46 grams and standard deviation .02
grams.
For a penny to be among the heaviest 10% of all pennies, what
must it weigh? (A sketch is often helpful for this type of
problem)
Supposeasampleof10penniesisrandomlyselectedfromthepopulationof
pennies. What is the probability that the average of this sample is
more than 2.47 grams?
Now, instead, if a sample of 30 pennies is randomly selected
from the population, what is the probability...

Weights (X) of men in a certain age group have a normal
distribution with mean μ = 190 pounds and standard
deviation σ = 20 pounds. Find each of the following
probabilities. (Round all answers to four decimal places.)
(a) P(X ≤ 220) = probability the weight of a
randomly selected man is less than or equal to 220 pounds.
(b) P(X ≤ 165) = probability the weight of a
randomly selected man is less than or equal to 165...

The local
bakery bakes more than a thousand 1-pound loaves of bread daily,
and the weights of these loaves varies. The mean weight is 1.2 lb.
and 2 oz., or 601 grams. Assume the standard deviation of the
weights is 25 grams and a sample of 46 loaves is to be randomly
selected.
(a) This
sample of 46 has a mean value of x, which
belongs to a sampling distribution. Find the shape of this sampling
distribution.

Pennies made before 1983 are 97% copper and 3% zinc, whereas
pennies made after 1983 are 3% copper and 97% zinc. Listed below
are the weights (in grams) of pennies from each of the two time
periods. Find the mean and median for each of the two samples,
then compare the two sets of results.
Before 1983:
3.1086
3.1038
3.1043
3.1588
3.1274
3.0772
After 1983:
2.4999
2.5027
2.4909
2.4847
2.4824
2.4951
The mean weight of the pennies made before 1983...
