Since the exposure measure (Nut Consumption) was not randomly assigned, review the data in table below (Table 1) and answer the questions that follow. a. For the primary association of interest (nut consumption and depressive symptoms), if you were informed that sex was a cause of the outcome (depressive symptoms), do you think, based on the information in the table, that sex is a potential confounder of this association? Yes or No? Explain your rationale.

I think sex is a confounder because the frequency of nut consumption is different between groups but the p-value is small so I am not so sure.
