An engineer is running a plant test on Line 2 and claims that
mean moisture content is out of
specification. The specification requires that mean moisture
content to be 5%. The engineer
decided to collect moisture analyses on 10 samples during this
testing period. These data
resulted in a mean value of 5.5% and a standard deviation of 1%.
Using a test level of 0.005
and answer the following questions.
a. Does this set of data support the engineer’s claim at the
specified test level?
b. If your conclusion in Part “a.” is wrong, what type of error did
you make?
c. Give a 95% confidence interval for the mean moisture
content.
d. With the conditions as given, what is the power if the true mean
moisture content is
4.5%?
e. With the conditions as given, if the true mean moisture content
is 4.0%, with a type 2
error of 0.05, how many samples should be taken? Use a sigma =
2.0%.

An operation manager at an electronics company wants to test
their amplifiers. The design engineer claims they have a mean
output of 495495 watts with a standard deviation of 1212 watts.
What is the probability that the mean amplifier output would
differ from the population mean by more than 1.91.9 watts in a
sample of 8888 amplifiers if the claim is true? Round your answer
to four decimal places.

An operation manager at an electronics company wants to test
their amplifiers. The design engineer claims they have a mean
output of 118 watts with a variance of 121 . What is the
probability that the mean amplifier output would differ from the
population mean by greater than 0.6 watts in a sample of 77
amplifiers if the claim is true? Round your answer to four decimal
places.

The manufacturer of a certain brand of pre-made hamburgers
claims that the mean fat content of its burgers is 12 grams.
Management is concerned that the true average fat content of the
burgers is higher than this amount. To investigate, they sample 20
burgers and find a mean fat content of 13.1 grams. Assuming that
the fat content of burgers is Normally distributed with a
population standard deviation of ? = 3.1 grams, is there evidence
that the true average...

A certain brand of cereal claims that the mean sodium content per serving is less than...
A certain brand of cereal claims that the mean sodium content
per serving is less than 235 mg and past research suggests that the
standard deviation is 10 mg. You find that a sample of 53 cereal
servings has a mean sodium content of 233 mg. Using a 0.10
significance level, what can you conclude about the brand’s
claim?
1) What type of hypothesis test is this?
2) State the hypotheses.
3) Calculate the value of the Test Statistic.

A food manufacturer claims that their new oat bran
muffin has a population mean calorie content of 250 calories with a
sample standard deviation of 10.1 calories. A government food
researcher believes the manufacturer's claim is too low and decides
to test the manufacturer's claim. A random sample of 25 muffins
yields a sample mean calorie content of 254.9 calories. The food
researcher decides to perform a hypothesis test at
α = 1 % to determine if it is
reasonable...

Candle-Line is an online retailer that does frequent A/B
testing. The process of running a test is as follows: The first
step is designing the test; this involves the web design team. The
test then waits for its turn to be run. Next, the test is run and
data is collected. Once the test is completed, the data must wait
for an available statistician. When a statistician is available,
she performs the analysis and generates a report. Tests originate
in...
