Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem, Also, post your own solution at the end.
For example, you may believe that the population mean number of times that adults go out for dinner each week is less than 1.5. Your data could be that you spoke with 7 people and found that they went out 2, 0, 1, 5, 0, 2, and 3 times last week. You then would choose to test this hypothesis at the .05 (or another) significance level. Assume a random sample.

My problem is:
I asked 10 teenagers how many times this monthnhave thely used a
land line phone.
My results are as following: 2,0,1,1,0,0,3,0,1,0
I'd like to propose that the population mean for the amount of
times that a teenager...

Think about a population proportion that you may be interested
in and propose a hypothesis test problem for this parameter. Gather
appropriate data and post your problem. Include the null and
alternative hypothesis, alpha value, p-value, and a conclusion.
Make sure that you use appropriate terminology, specify whether you
are using the classical method or the p-value method, and fully
explain your solution.

Think about two population means that you may be interested in and propose a hypothesis test problem for this parameter.
write a hypothesis test problem. Post your problem with a
solution.
Think about two population means that you may be interested in
and propose a hypothesis test problem for this parameter. For
example, you may believe that the average family size in Illinois
is greater than the average family size in Wisconsin. Your data
could be that you spoke with 20 people (10 in Illinois and 10 in
Wisconsin) and found the following family sizes: 5, 6, 5, 2, 3,...

you will propose a hypothesis test that will test a
claim that is of interest to you in the business world. Then
describe how you would gather a representative sample to test that
claim.
1. state the claim you wish to investigate in your own words.
2. write a null and alternative hypothesis.
3. describe how you will gather a representative sample to test
your claim.
4. state the type of test you would use for example,
TTest,1PropZTest, etc.

Suppose you wish to perform a hypothesis test for a population
mean. Suppose that the population standard deviation is known, the
population distribution is Normal, and the sample is small. Would
you perform a z-test or t-test?
a.The z-test is appropriate.
b.Either test is appropriate.
c.The t-test is appropriate.
d.Neither test is appropriate.

Suppose you have conducted a two tailed hypothesis test for the
population mean where the population standard deviation was
unknown, the population data is normally distributed, and the
sample size is 8. Your test statistic is -1.70. At a level of
significance of 0.10, what is your conclusion?
A. Reject the null hypothesis since the test statistic is
between the critical values.
B. Do not reject the null hypothesis since the test statistic is
between the critical values.
C. Reject...

Assume you want to test the hypothesis that the mean weight of
the male student population is 160 lbs
If we assume that the standard deviation has a known value of 12
lbs and we want to test with a confidence level of 95%
to. What sample size should we use if we want one to have a
probability of making a type II error of no more than 5% in the
test when the actual mean is 163 lbs?...
