Answer:
B. 107
Explanation:
Demand for soccer balls at a new sporting goods store is forecasted using the following regression equation: Y = 98 + 2.2X where X is the number of months that the store has been in existence. Let April be represented by X = 4. April is assumed to have a seasonality index of 1.15. What is the forecast for soccer ball demand for the month of April (rounded to the nearest integer)?
y = 98 + 2.2x when x = 4
y = 98 + 2.2(4)
y = 98 + 8.8
y = 106.8
