Answer #1

A nutritionist claims that the mean tuna consumption by a person
is 3.2 pounds per year. A sample of 80 people shows that the mean
tuna consumption by a person is 2.9 pounds per year. Assume the
population standard deviation is 1.13 pounds. At alphaequals 0.04,
can you reject the claim?

D-decide to reject or fail to reject the null hypothesis

A nutritionist claims that the mean tuna consumption by a person
is 3.9 pounds per year. A sample of 50 people shows that the mean
tuna consumption by a person is 3.5 pounds per year. Assume the

A nutritionist claims that the mean tuna consumption by a person
is 3.5 pounds per year. A sample of 90 people shows that the mean
tuna consumption by a person is 3.4 pounds per year. Assume the
population standard deviation is 1.04 pounds. At alphaequals0.02,
can you reject the claim? (a) Identify the null hypothesis and
alternative hypothesis.

A nutritionist claims that the mean tuna consumption by a person
is 3.4 pounds per year. A sample of 80 people shows that the mean
tuna consumption by a person is 3.1 pounds per year. Assume the
population standard deviation is 1.06 pounds. At alphaequals0.08,
can you reject the claim? (a) Identify the null hypothesis and
alternative hypothesis. A. Upper H 0: munot equals3.1 Upper H
Subscript a: muequals3.1 B. Upper H 0: muless than or equals3.1

4. A consumer group claims that the mean annual consumption of
coffee by a person in the United States is 25 gallons. A random
sample of 100 people in the United States has a mean annual coffee
consumption of 22.5 gallons. Assume the population standard
deviation is 4.8 gallons. At ? = 0.05, can you reject the claim? Be
sure to set up your hypothesis test, solve using the p-value, and
interpret your results

A company claims that the mean monthly residential electricity
consumption in a certain region is more than 870 kilowatt-hours
(kWh). You want to test this claim. You find that a random sample
of 63 residential customers has a mean monthly consumption of 900
kWh. Assume the population standard deviation is 130 kWh. At alphaα
equals=0.10, can you support the claim?

A company claims that the mean monthly residential electricity
consumption in a certain region is more than 870 kilo Watt-hours
(kWh). You want to test this claim. You find that a random sample
of 69 residential customers has a mean monthly consumption of 910
kWh. Assume the population standard deviation is 120 kWh. At alpha
αequals=0.10 can you support the claim? Complete parts (a)
through (e).

In a random sample of 22 adults in the U.S., you find that the
mean waste generated per person per day is 4.5 pounds with a
standard deviation of 1.2 pounds. At @=0.1, can you support the
claim that the mean amount of waste generated by adults in the U.S.
is more than 4 pounds per day?

5) An environmentalist claims that the mean waste recycled by
adults in the United States is more than 1 pound per person per
day. You wish to test this claim. You find the mean waste recycled
per person per day for a random sample of 12 adults in the United
States is 1.146 pounds per day with a standard deviation of .12
pounds per day. At α = .05, can you support the environmentalists
claim?

A research company desires to know the mean consumption of meat
per week among people over age 29. A sample of 2092 people over age
29 was drawn and the mean meat consumption was 2.9 pounds. Assume
that the population standard deviation is known to be 1.4 pounds.
Construct the 95% confidence interval for the mean consumption of
meat among people over age 29. Round your answers to one decimal
place.
