- Consider the following statement:
Squirrels prefer sunflower seeds over acorns.
Is the above statement a valid hypothesis?
If you think yes, describe how you would test this hypothesis. If you think no, explain why you think it is not a valid hypothesis.
- Why was it important to measure multiple leaves in each group? (In other words, why have replicates?) Why not just measure one leaf in the high-light group, one leaf in the low-light group, and then compare their widths to determine whether different levels of sunlight exposure affect leaf width?
- Why was it important to choose leaves randomly?
- Some of you may have obtained a large difference in mean widths between your two plant groups, while some of you may have obtained only a small difference. Whichever it is, do you think that there is enough of a
difference between your means to be able to confidently conclude that light affects leaf width? Explain in one or two sentences.
