Question

The manager of a Papa John's wants to determine whether the amount of tomato sauce contained in a 130 oz can purchased from the supplier averages less than 130 oz. It is known from the manufacturer's specifications that the standard deviation of the amount of sauce is equal to 1.5 oz. A random sample of 25 cans are selected, and the mean amount of amount per bottle can is found to be 128.4 oz. Conduct the appropriate hypothesis test at alpha = .05.

Answer #1

The manager of a paint supply store wants to estimate the actual
amount of paint contained in 1-gallon cans purchased from a
nationally known manufacturer. The manufacturer's specifications
state that the standard deviation of the amount of paint is equal
to 0.01 gallon. A random sample of 50 cans is selected, and the
sample mean amount of paint per 1-gallon can is 0.996 gallon.

A bottled water distributor wants to determine whether the mean
amount of water contained in 1-gallon bottles purchased from a
nationally known water bottling company is actually 1 gallon. You
know from the water bottling company specifications that the
standard deviation of the amount of water per bottle is 0.03
gallon. You select a random sample of 100 bottles, the mean amount
of water per 1-gallon bottle is 0.994 gallon.
a. Is there evidence that the mean amount is different...

The manager of a gasoline supply corporation wants to estimate
the actual amount of gasoline contained in standard 42-gallon
barrels purchased from a nationally known manufacturer. The
manufacturer’s specifications state that the amount of gasoline is
normally distributed with a standard deviation of 0.65 gallon. A
random sample of 25 barrels is selected, and the sample mean amount
of gasoline per 42-gallon barrel is 42.15 gallons. Construct a 90%
confidence interval estimate for the population mean amount of
gasoline contained...

The manager of a paint supply store wants to determine whether
the mean amount of paint contained in 1-gallon cans purchased from
a nationally known manufacture is actually 1 gallon. You know from
the manufactures specification that the standard deviation of the
amount of paint is 0.02 gallon. You select a random sample of 50
cans, and the mean amount of painter per 1-gallon can is 0.995.
(a) Conduct a hypothesis test to determine whether or not
there’s enough evidence...

Q1-Suppose a wholesaler of paints wants to estimate the actual
amount of paint contained in 10 kg cans purchased from a paint
manufacturing company. It is known from the manufacturer's
specifications that the standard deviation of the amount of paint
is equal to 0.05 kg. A random
sample of 49 cans is selected yields an average amount of paint per
10 kg can is 0.995 kg. What
will be the margin of error when constructing a 97%
confidence interval for...
