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.   

 

Hint - Use the following formulas to calculate the ‘m' and 'c' values.
ΝΣxy- Σ×Σy
