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

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

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.

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).
