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.

For this study, we should use
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 αα
Base on this, we should hypothesis
As such, the final conclusion is that...
- There is insufficient evidence to support the claim that course delivery type is a factor in final exam score.
- There is sufficient evidence to support the claim that course delivery type is a factor in final exam score.
