Explain the procedure
for testing a hypothesis using the P-value approach? What is the
criterion for judging whether to reject the null hypothesis?
6. What does the level
of significance represent in a test of hypothesis? Give an
example.
7. Explain the
difference between "accepting" and "not rejecting" a null
hypothesis.
What is the rejection rule using the p-value approach to
Hypothesis Testing?
What is the rejection rule using the critical value approach to
Hypothesis Testing?
For the following, Use the five-step approach to hypothesis
testing found on page 8-16. It states. You can use excel to compute
the data or you can do it by hand. The YouTube videos provided in
the links will walk you through the steps to complete the following
problems.
State the hypothesis and identify the claim.

H1:
Find the critical value and determine what error level to use.
For all the problems on this homework use an alpha level...

(a) What is the relationship of the p-value and hypothesis
testing?
(b) What is a p-value threshold of 0.05 mean? (in words)
(c) Why do you think that a p-value of 0.05 is used so often as a
threshold? What is a situation when that value would be too large
(i.e. a value much lower than 0.05 should be used)?

Conduct a hypothesis test (using either the p-Value Approach or
the Critical Value Approach) to determine if the proportion of all
recent clients is more dissatisfied than the traditional level of
dissatisfaction. Use α = 0.08. Do not forget to include the
correctly worded hypotheses and show all the steps required to
conduct the hypothesis test. 92 out of sample of 200 were
dissatisfied
