whats the answer to question four and five

Use the following problem statement to answer questions 1-6. A manager wants to make annual purchasing plans for gardening items. One of the items the company stocks is Fast-Grow, a liquid fertilizer. The sales of the item are seasonal, Quarterly demand (in cases) for the past two years is shown in the table. The manager knows that the expected sales for Fast-Grow are 1,600 cases for year 3. The actual demands from Quarter 1 of year 1 to Quarter 4 of year 2 are shown in the table below. Use the multiplicative seasonal method to prepare a forecast for each quarter of the year. Round to four decimal places when you calculate all centered averages and seasonal indexes. [Note: Seasonal index =( sales)/(centered average). Four-period centered average =(Dt+Dt+1+Dt+2+Dt+3)/4. Adjusted seasonal index =(( each avg. index )(4))/( sum of avg. indexes)]. What is the two-period centered average for Q2 of year 2? 132.0000 152.0000 Question 5 What is the two-period centered average for Q4 of year 1 ? 153.5000 133.5000
