Question

Suppose the horses in a large stable have a mean weight of 1124lbs, and a standard deviation of 150lbs. What is the probability that the mean weight of the sample of horses would differ from the population mean by less than 7lbs if 41 horses are sampled at random from the stable? Round your answer to four decimal places.

Answer #1

Suppose the horses in a large stable have a mean weight of
1128lbs, and a standard deviation of 58lbs.
What is the probability that the mean weight of the sample of
horses would be less than 1136lbs if 37 horses are sampled at
random from the stable? 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.

Suppose babies born in a large hospital have a mean weight of
3685 grams, and a variance of 3330,625.
If 113 babies are sampled at random from the hospital, what is
the probability that the mean weight of the sample babies would
differ from the population mean by less than 50 grams? Round your
answer to four decimal places.

Suppose cattle in a large herd have a mean weight of 1312lbs and
a standard deviation of 54lbs.
What is the probability that the mean weight of the sample of
cows would be greater than 1324lbs if 117 cows are sampled at
random from the herd? 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.

Suppose babies born in a large hospital have a mean weight of
3200 grams, and a standard deviation of 526 grams. If 100 babies
are sampled at random from the hospital, what is the probability
that the mean weight of the sample babies would differ from the
population mean by less than 50 grams?

5. Horses in a stable have a mean weight of 950 pounds with a
standard deviation of 77 pounds. Weights of horses follow the
normal distribution. One horse is selected at random.
a) What is the probability that the horse weighs less than 900
pounds?
b) What is the probability that the horse weigh more than 1,100
pounds?
c) What is the probability that the horse weighs between 900 and
1,100 pounds?
d) What weight is the 90th percentile? (Round...

Suppose babies born in a large hospital have a mean weight of
3831 grams, and a variance of 108,900. If 65 babies are sampled at
random from the hospital, what is the probability that the mean
weight of the sample babies would be less than 3882 grams? Round
your answer to four decimal places.

supposed cattle in a large herd have a mean weight of 1366 pounds
and have a standard deviation of 59 pounds what is the probability
that the mean weight of the sample of cows would be less than 1356
pounds if 39 cows are sampled at random from the herd. round your
answr to four decimal places

suppose cattle in a large herd have a mean weight of 914 lbs and a
standard deviation of 149lbs what is the probability that the mean
weight of the sample of cows would differ from the population means
by greater than 7lbs if 57 cows are samples at random from the
herd?
