c) Classify the **hypothesis** test as **two**-**tailed**, left-**tailed** or right-**tailed**
This is a **two**-**tailed** test, since there is no direction specified for the test. The solution discusses **hypothesis** **testing** and unemployment levels.

State the claim mathematically. Then write the null and alternative **hypothesis**. Determine whether the **hypothesis** test is left-**tailed**, right-**tailed**, or **two**-**tailed**.

The **two**-**tailed** P value equals 0.0658
b. The **two**-**tailed** P value equals 0.0843, so the required one-**tailed** p-value is 0.0843/2 = 0.042155 This solution finds the p-value for each of the **hypothesis**-**testing** situations.

a) What is your null **hypothesis**? Alternate **hypothesis**?
Null **Hypothesis** H0: mean = 75
Alternate **Hypothesis** Ha: mean is not equal to 75
b) Is this a one-**tailed** or **two**-**tailed** **hypothesis**?
**Two**-**tailed** test
c) What is your obtained z?

choice questions on **testing** of **hypothesis**

A **two**-**tailed** **hypothesis** test at the 0.10 level of significance where the initial probability calculated for the test statistic is 0.047. (Don't forget to make the adjustment needed for the **two** **tailed** test.)
4.

How would you arrive at a probability value (given in the z-score table) to reflect a **two**-**tailed** **hypothesis**? How would you arrive at a probability value to reflect a one-**tailed** **hypothesis**?

Indicate the type of test to be performed (left-**tailed**, right-**tailed**, or **two** **tailed**)
B) Provide a statement in terms of the **hypothesis** **testing** process in this problem that would signify a Type I Error has been committed.

I will provide the null and research hypotheses and Type 1 and Type 2 errors for both **two**-**tailed** and one-**tailed** **hypothesis** **testing** situations.

Is the alternative **hypothesis** one-**tailed** or **two**-**tailed**?
The alternative **hypothesis** is one **tailed** because it has a '<' sign in it.
d. What is the p-value?
