what is the correct answer? learnsmart is counting these numbers as incorrect.

PA 15-4 A police station had to deploy a police officer... A police station had to deploy a police officer for an emergency multiple times in the last four evenings. The table below shows the number of emergencies each evening (Round your answers to 3 decimal places.) Forecast for tomorrow Weekday Number of calls each day (calls) Monda Tuesday Wednesda Thursday 12 8.400 8.580 6.906 7.234 Complete the "Forecast for tomorrow" column in the table above. Use an exponential smoothing a. forecasting approach, with =0.3 and a forecast for Monday of 12. (Round your answer to 3 decimal places.) What would be their forecast for Friday using the same exponential smoothing forecasting approach? 7.764

Explanation / Answer

EMA Forecast for today = (calls of yesterday – EMA for yesterday)* + EMA for yesterday

EMA for Tuesday = (9-12)*.3 + 12 = 11.100

EMA for Wednesday = (3-11.1)*.3 + 11.1 = 8.670

EMA for Thursday = (8-8.67)*.3 + 8.67 = 8.469

EMA for Friday = (9-8.469)*.3 + 8.469 = 8.628

So, table prepared are as follows:
