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=0.01α=0.01.
H0: μ1=μ2=μ3H0: μ1=μ2=μ3
H1:H1: At least two of the means differ from each other.
- For this study, we should use Incorrect
- The test-statistic for this data = (Please show your answer to 3 decimal places.)
- The p-value for this sample = (Please show your answer to 4 decimal places.)
- The p-value is Incorrect αα
- Base on this, we should Incorrect hypothesis
- As such, the final conclusion is that...
- There is sufficient evidence to support the claim that treatment type is a factor in recovery time for pneumonia.
- There is insufficient evidence to support the claim that treatment type is a factor in recovery time for pneumonia.
