Please create a specific business scenario which is appropriate for hypothesis testing of population mean with population standard deviation sigma given. Follow all the steps in the textbook (from hypothesis determination to result interpretation at least) to test the hypothesis.
Can I please get another exmaple other than the one of Jane and the other one posted i dont understand them very much.

Please create a specific business scenario which is appropriate
for hypothesis testing of population mean with population standard
deviation sigma given. Follow all the steps in the textbook (from
hypothesis determination to result interpretation at least) to test
the hypothesis.
Step 1.
Develop the null and alternative hypotheses.
Step 2.
Specify the level of significance.
Step 3.
Collect the sample data and compute the value of the test
statistic.
Step 4.
Use the value of the test statistic to compute...

(30 pts) Write an appropriate hypothesis testing problem that’s
related to your article for the population small sample mean.. You
are free to choose a one‐sided or a two‐sided alternative. (10 pts)
a. State the null and alternative hypotheses. (5 pts) b. Compute
the test statistic under the assumption that the null hypothesis is
true. Use two decimal places for ? scores and three decimal places
for ? and ? values. (5 pts) c. Compute the ?‐?????. (5 pts) d....

Please conduct a Hypothesis test in the following scenario to
determine if the population slope is statistically significant.
State the appropriate test statistic, the critical values, and
whether or not you can reject a null hypothesis that the population
slope is zero.
Use a 1% significance level. Suppose that you collected data to
determine the relationship between the amount of time a person
spends online as an independent variable and the amount of money a
person spends online as the...

Business Turnarounds" Please respond to the following:
Create a scenario in which a business’s most attractive option
may be to declare bankruptcy identifying the benefits and
consequences of the filing. Provide a rationale with your
response.
Create a scenario in which you would sell a portion of your
financially troubled business venture from a fashion boutique to a
turnaround management company in hopes of getting the business back
on track. Provide support for how this may be a desirable
option.

Question 3: Hypothesis Testing about the population mean
(μ)
A researcher claims that the average weekly spending for lunch by
commuting students in US colleges is usually higher in winter
semester than the of average of $30 in the prior fall semester. To
verify this claim a sample of 100 commuting students were randomly
selected in spring semester and their average weekly spending was
reported as $32.5. From historical experience the population
standard deviation of weekly spending by commuting...

Explain how a hypothesis testing for a mean is similar to a
hypothesis test for a proportion. Then explain how z-test for a
mean is different than a t-test for a mean.

Perform an appropriate hypothesis test for a population mean
using the p-value approach.
Last year, the mean running time for a certain type of
flashlight battery was 8.5 hours. This year, the manufacturer has
introduced a change in the production method which he hopes will
increase the mean running time. A random sample of 4 0 of the new
light bulbs was obtained and the mean running time was found to be
8.7 hours. Do the data provide sufficient evidence...
