After graduating from college with a degree in mathematical statistics, Ann Preston has been hired by the Monty Ward Company to apply statistical methods for forecasting the company's sales. For one of the company's products, the moving-average method based upon sales in the 10 most recent months already is being used. Ann's first task is to update last month's forecast to obtain the forecast for next month. She learns that the forecast for last month was 1,551 and that the actual sales then turned out to be 1,532. She also learns that the sales for the tenth month before last month was 1,632. What is Ann's forecast for next month?
