Question

A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. Calculate the probability of a type II error if the true mean elongation is 11.5 kilograms and

- α = 0.05 and
*n*= 4 - α = 0.05 and
*n*= 16

Answer #1

a)

P( Type II error) = P( not rejecting H 0 when it is false)

b)

P( Type II error) = P( not rejecting H 0 when it is false)

A textile fiber manufacturer is investigating a new drapery
yarn, which the company claims has a mean thread elongation of 12
kilograms with a standard deviation of 0.5 kilograms. The company
wishes to test the hypothesis H0: mu >=12 against H1: mu < 12
using a random sample of n=14 specimens. Calculate the P-value if
the observed sample mean is 11.1. . Round your final answer to five
decimal places (e.g. 98.76543). the decimal please.

A textile fiber manufacturer is investigating a new drapery
yarn, which the company claims has a mean thread elongation of 12
kilograms with a standard deviation of 0.5 kilograms. The company
wishes to test the hypothesis against , using a random
sample of four specimens. (Note: the difference between the
computations for the two-sided alternative hypothesis shown in the
video and this one-sided hypothesis is that you don't multiply by 2
to allow for the symmetry.) What is the type I...

Please be clear and explain! Thanks!
9-‐7: A textile fiber manufacturer is investigating a new
drapery yarn, which the company claims has a mean thread elongation
of 12 kilograms with a standard deviation of 0.5 kilograms. The
company wishes to test the hypothesis H0: μ=12 against H1: μ<12,

A manufacturer claims that the average tensile strength of
thread A exceeds the average tensile strength of thread B by at
least 12 kilograms. To test his claim, 50 pieces of each type of
thread are tested under similar conditions. Type A thread had an
average tensile strength of 86.7 kilograms with known standard
deviation of σA = 6.28 kilograms, while type B thread had an
average tensile strength of 77.8 kilograms with known standard
deviation of σB = 5.61...

5. A manufacturer claims that the mean tensile strength of
thread A exceeds the average tensile strength of thread B. To test
his claim, 16 sample pieces of each type of thread are tested under
similar conditions. Type A thread had a sample average tensile
strength of 185 kilograms with a standard deviation of 6 kilograms,
while type B thread had a sample average tensile strength of 178
kilograms with a standard of 9 kilograms. Assume that both
populations are...

A major automobile company claims that its New electric powered
car has an average range of more that 100 miles. A random sample of
50 new electric cars was selected to test the claim. Assume that
the population standard deviation is 12 miles. A 5% level of
significance will be used for the test.
A) What would be the consequences of making a Type II error in
this problem?
B) Compute the Probability of making a Type II error if...

A manufacturer has developed a new fishing line, which the
company claims has a mean breaking strength of 14 kilograms with a
standard deviation of 1.7 kilograms. Believing the mean breaking
strength is less than what company has claimed, a customer
protection agency took a random sample of 20 such fishing lines and
found that the mean breaking strength for this sample is 14.5
kilograms. Given the breaking strength of all such lines have a
normal distribution, test whether the...

A research engineer for a tire manufacturer is
investigating tire life for a new rubber compound. She has built 10
tires and tested them to end-of-life in a road test. The sample
mean and standard deviation are 61,492 and 3035 kilometers,
respectively.
(a) Can you conclude, using α = 0.05, that the standard
deviation of tire life exceeds 3000 km?
(b) Find the P-value for this test.
(c) Find a 95% lower confidence bound for σ and use it
to...

A manufacturer is trying to determine if a new chemical it is
using changes the mean hourly yield of its production process.
Historically, the mean level of production was a yield of 3 kg per
hour. A sample of 16 hours of production finds a mean of 2.77 kg
per hour and a standard deviation, s, of 0.3 kg per
hour.
a) At the α=0.01 level of significance, test whether or not the
new chemical has changed the mean hourly...

Question 1
The production manager of a camera manufacturer claims that
their
latest digital camera is able to focus in just 0.0025 seconds on
the
average. A random sample of the focus time in seconds for 20
cameras
is collected and the times are recorded as follows:
0.0033
0.0028
0.0021
0.0032
0.0020
0.0025
0.0026
