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.
