The accompanying data file contains the net profit (Net_Profit), counter sales (Counter_Sales), and drive-through sales (Drive_Sales) for a chain of 100 fast-food restaurants. All variables are measured in millions of dollars. Click here for the Excel Data File a-1. Calculate the sample standard deviation for counter sales and drive-through sales. Note: Round your answers to 4 decimal places. Enter your answers in dollars, rather than in millions of dollars (e.g. $4,000,000 would be entered as $4). Sample standard deviation Counter sales Drive-through sales a-2. According to this measure of dispersion, which variable exhibited higher variability? O Counter sales
