For your data, use the linear forecasting model which is y = mx + c to calculate and discuss the followings:

1. Show the steps of calculation of m value and discuss the answer.
2. Show the steps of calculation of c value and discuss the answer.
3. Using the calculated 'm' and 'c' values, forecast the wind speed for day 11 and day 12.
