From the data below, calculate the upper and lower Bollinger bands, which represent plus (or minus) two standard deviations of the 20-day simple moving average added (subtracted) from the 20-day simple moving average. If the daily price approaches or exceeds the upper Bollinger band, traders will look for a continued upward movement in the stock price. Note: Do not round intermediate calculations. Round your answers to 2 decimal places.
