Record the data, and for EACH sample, find the sample mean, the sample standard deviation and the five-number summary. Compare your two samples creating boxplots or histograms.
Summarize your results in a paragraph, including a description of how you collected your data and your interpretation of the results. Does it appear that the two populations are similar, or different? Submit one file and save your document as a pdf file.
