Assume that all distributions are normal, the three population standard deviations are all the same, and the data was collected independently and randomly. Use a level of significance of α=0.1α=0.1.


H0: μ1=μ2=μ3H0: μ1=μ2=μ3
H1:H1: At least two of the means differ from each other.

1. For this study, we should use


2. The test-statistic for this data =  (Please show your answer to 3 decimal places.)


3. The p-value for this sample =  (Please show your answer to 4 decimal places.)


4. The p-value is     αα


5. Base on this, we should      hypothesis


6. As such, the final conclusion is that...
