The trade volume of a stock is the number of shares traded on a given day. The data in the first accompanying table, in millions (so that 6 16 represents 6,160,000 shares traded), represent the volume of a PepsiCo stock traded for a random sample of 38 trading days in 2018. A second random sample of 38 days in 2018 resulted in the data in the second accompanying table Complete parts (a) through (d). Click here to view the data for sample 1.
