consider which step of the hypothesis test procedure makes a
decision on the statistical hypothesis and which step determines
the substantive nature of the results of the hypothesis test?
What is statistical hypothesis? Define the following terms with
reference to testing of a hypothesis-
Null and Alternative Hypothesis
Critical Region
Significance Level
Types of Hypothesis Tests
Two types of Errors in Hypothesis Tests
Discuss how the concept of statistical independence underlies
statistical hypothesis testing in general. Based on statistical
analysis, are we justified in asserting that two variables are
statistically dependent? Why or why not? Explain why researchers
typically focus on statistical independence rather than statistical
dependence.

Consider the seven steps of hypothesis testing. The final step
in the hypothesis-testing process involves deciding whether to
reject the null hypothesis. Assuming thenull hypothesis is not
rejected, what is the difference between accepting the null
hypothesis and failing to reject it? Explain your reasoning.
Hypothesis Testing (One Sample- proportion)
using the 5 step process:
Use hypothesis testing to test the claim that the percentage of
women who use Cannabis on a regular basis is more than 26%. A
random sample of 200 women found that 64 of them used Cannabis on a
regular basis. Use a level of significance of 0.10.
What are the steps in hypothesis testing?
What is the goal of hypothesis testing?
What are null and alternative hypotheses?
In §9.2 the concepts of Type I and Type II errors are
introduced.Consider the situation where a husband and wife go to
the doctor’s office to each get some tests run and the doctor
accidentally mixes up their charts. The doctor comes into the
exam room with the results of the tests and declares that the wife
is NOT pregnant but...

which step you feel will be the most important to the process and
why.
2) Give a real life example of how you might use hypothesis
testing.
