Company claims to fill cereal boxes on average with 24 oz. of
cereal with a standard deviation of 2 oz. The company is satisfied
if the average weight of cereal per box is within 0.6 oz. of the
advertised weight. What is the probability that the company is not
satisfied with the average weight of cereal based on a sample of
100 boxes?

The weights of a certain brand of cereal boxes are normally
distributed. The mean weight of a SAMPLE of 13 boxes was 14.91
ounces with a sample standard deviation of .22 ounces. The margin
of error on a 90% confidence interval would be smaller than the
margin of error on a 95% confidence interval. True or false?

1) A manufacturer of cereal claims that the mean weight of a
particular type of box of cereal is 1.2 pounds. A random sample of
71 boxes reveals a sample average of 1.186 pounds and a sample
standard deviation of .117 pound. Using the .01 level of
significance, is there evidence that the average weight of the
boxes is different from 1.2 pounds?
Is the test statistic for this test Z or t?
Select one:
a. t
b. z

A cereal manufacturer claims that boxes of its cereals weigh 20
oz. on average with a population standard deviation of 0.5 oz. A
random sample of 100 boxes is selected. What is the probability
that sample mean is between 19.9 and 20.1 oz. Assume that it
follows normal distribution.

On the back of its cereal boxes, Tiger Cereal Company offers a
premium to its customers. The premium, a toy truck, may be claimed
by sending in $1 plus 10 coupons; one coupon is included in each
box of cereal sold. Tiger estimates, based on past experience, that
60% of the coupons will be redeemed. During 2016, Tiger purchased
240,000 toy trucks at $1.25 each for the premium promotion and sold
5,000,000 boxes of cereal, for cash, at $1.80 per...

Suppose that the weight of open boxes of cereal in a home with
children is uniformly distributed from two to six pounds with a
mean of four pounds and standard deviation of 1.1547. We randomly
survey 64 homes with children.
a) Find the probability that the total weight of open boxes is less
than 257 pounds. (Round your answer to four decimal places.)
b) Find the 45th percentile for the total weight of
open boxes of cereal. (Round your answer...

Lloyd's Cereal company packages cereal in 1 pound boxes (16
ounces). A sample of 25 boxes is selected at random from the
production line every hour, and if the average weight is less than
15 ounces, the machine is adjusted to increase the amount of cereal
dispensed. If the mean for 1 hour is 1 pound and the standard
deviation is 0.2 pound, what is the probability that the amount
dispensed per box will have to be increased?

A machine fills cereal boxes. A random sample of 6 boxes had a
mean of 20.25 oz. The distribution is assumed to be NORMAL with
KNOWN standard deviation of 0.21 oz.
