Ho: µ1 = H2 = µ3 H: At least two of the means differ from each other. 1. For this study, we should use ANOVA 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 greater than alpha 5. Base on this, we should fail to reject the null hypothesis v 6. As such, the final conclusion is that... a hypothesis O There is sufficient evidence to support the claim that treatment type is a factor in recovery time for pneumonia.

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 a = 0.01.
Ho: µi = µ2 = µ3
H: At least two of the means differ from each other.
1. For this study, we should use ANOVA
