A biologist is investigating the effect of potential plant hormones by treating 20 stem segments. At the end of the observation period he computes the following length averages:

Compound X= 1.18

Compound Y= 1.17

Based on these mean values he concludes that there are no treatment differences.

1) Are you satisfied with his conclusion?Why or why not?

2) If he asked you for help in analyzing these data, what statistical method would you suggest that he use to come to a meaningful conclusion about his data and why?

3) Are there any other questions you would ask him regarding his experiment, data collection, and analysis methods?
