in the United States and territories at the 0.05 level of significance.
Step 1: Clearly state a null and alternative hypothesis, identify the claim, and the type
of test. (Circle the appropriate symbol or erase the incorrect symbols).
Ho: μ ≥ ≤ = ________
Ha: μ < > ≠ _________
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 births is _________ (GREATER THAN/LESS THAN/EQUAL
TO) 5000 in the United States and territories at the 0.05 level of significance.
Hypothesis Test #2:
Determine if there is sufficient evidence to conclude the average amount of deaths is equal to
6000 in the United States and territories at the 0.10 level of significance.

First, you will need to complete an order form. It's not difficult but, if anything is unclear, you may always chat with us so that we can guide you through it. On the order form, you will need to include some basic information concerning your order: subject, topic, number of pages, etc. We also encourage our clients to upload any relevant information or sources that will help.
Complete the order form
Once we have all the information and instructions that we need, we select the most suitable writer for your assignment. While everything seems to be clear, the writer, who has complete knowledge of the subject, may need clarification from you. It is at that point that you would receive a call or email from us.
