HELP PLEASE 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.
