1. Calculate the Pearson correlation between hand and foot size for members of this STA-201 class. Graph the relationship, determine a hypothesis to test this relationship, and statistically test this hypothesis using alpha=0.05. Interpret all results in a paragraph citing the appropriate statistics.
