Hypothesis Test #4:

Determine if there is sufficient evidence to conclude the average amount of divorces is less than or equal to 4000 in the United States and territories at the 0.10 level of significance.

Step 1: Clearly state a null and alternative hypothesis, identify the claim, and the type of test.

Ho: =

Ha: < >

Circle One: Left Tailed Test Right Tailed Test Two-Tailed Test

Step 2: Determine the Rejection Region

Pick ONE multiple choice answer below and fill in the critical value. Round Critical Value to two decimal places.

a) Reject Ho if Z ___________

b) Reject Ho if Z ___________

c) Reject Ho if Z is less than ___________ or greater than ___________ .

Step 3: Give the value of the test statistic and the P-Value

Z = ___________________ P-Value= __________________

Step 4: Clearly state your conclusion

Circle One: Reject the Null Hypothesis..... OR...... Fail to Reject the Null Hypothesis

Step 5: Explain what your conclusion means in context of the data.

There _______ (IS/IS NOT) sufficient statistical evidence to ________ (SUPPORT/REJECT) the claim that the average amount of divorces is _________ (GREATER THAN/LESS THAN/EQUAL TO) 4000 in the United States and territories at the 0.10 level of significance.
