Question

A scientist wants to know if there is a meaningful difference between two groups of gels that grow bacteria. He randomly selects five gels from each group, and counts the number of bacteria spots on each gel:
Group A: 9, 12, 13, 14, 17



Group B: 6, 5, 8, 13, 8



Is there a meaningful difference between the two groups? Show all calculations that lead to your answer.

Answer 1

The difference between the numbers of group A and group B will be 3, 1, 1, 3 and -1, 3, 5, -5. Then there is no meaningful difference between the two groups.
