Answer #1

The mean weight of an adult is 67 kilograms with a variance of
81.
If 57 adults are randomly selected, what is the probability that
the sample mean would differ from the population mean by greater
than 1.5 kilograms? Round your answer to four decimal places.

The mean weight of an adult is 70 kilograms with a standard
deviation of 8 kilograms. If 87 adults are randomly selected, what
is the probability that the sample mean would differ from the
population mean by more than 1.2 kilograms? Round your answer to
four decimal places.

The mean weight of an adult is 62 kilograms with a variance of
144. If 195 adults are randomly selected, what is the probability
that the sample mean would be less than 59.5 kilograms? Round your
answer to four decimal places.

Suppose cattle in a large herd have a mean weight of 1169lbs and
a variance of 17,161.
What is the probability that the mean weight of the sample of
cows would differ from the population mean by greater than 12lbs if
145 cows are sampled at random from the herd? Round your answer to
four decimal places.

The
mean cost of a five pound bag of shrimp is 40 dollars with a
variance of 36.
If a sample of 43 bags of shrimp is randomly selected, what is
the probability that the sample mean would differ from the true
mean by more than 2.5 dollars? Round your answer to four decimal
places.

The mean cost of a five pound bag of shrimp is 42 dollars with a
variance of 49.
If a sample of 54 bags of shrimp is randomly
selected, what is the probability that the sample mean would differ
from the true mean by more than 1.4 dollars? Round your
answer to four decimal places.

A racing car consumes a mean of 114 gallons of gas per race with
a variance of 49 . If 33 racing cars are randomly selected, what is
the probability that the sample mean would differ from the
population mean by greater than 1.1 gallons? Round your answer to
four decimal places.

The mean cost of a five pound bag of shrimp is 50 dollars with a
variance of 64. If a sample of 43 bags of shrimp is randomly
selected, what is the probability that the sample mean would differ
from the true mean by greater than 1 dollar? Round your answer to
four decimal places.

The mean cost of a five pound bag of shrimp is 47 dollars with a
variance of 36.
If a sample of 43 bags of shrimp is randomly
selected, what is the probability that the sample mean would differ
from the true mean by greater than 1.4 dollars?
Round your answer to four decimal places.

Suppose the horses in a large stable have a mean weight of 873
lbs, and a variance of 17,161.
What is the probability that the mean weight of the sample of
horses would differ from the population mean by less than 15 lbs if
50 horses are sampled at random from the stable? Round your answer
to four decimal places.
