A hospital wants to determine if the type of treatment for pneumonia is a factor in recovery time? The table below shows the number of days to recovery for several randomly selected pneumonia patients that had various types of treatment.

Sent Home With Medicine	A Few Hours in the Hospital	Overnight Hospital Stay
25	16	8
15	8	16
15	24	10
17	20	6
17	16	10
28	20	17
12	17	13
26	23

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.
Incorrect
