Help with Part C The linear trend forecasting equation for an annual time series containing 45 values (from 1963 to 2007) on netsales (in billions of dollars) is shown below. Complete (a) through (e) below.Y = 4.8+1.3X₁a. Intepret the Y-intercept, bo. Which statement below is the interpretation of the Y-intercept?A. The Y-intercept bo = 1.3 reflects the predicted net sales in 1963.B. The Y-intercept b = 1.3 indicates that sales are predicted to increase by $1.3 billion/year.C. The Y-intercept bo = 4.8 reflects the predicted net sales in 1963.D. The Y-intercept bo = 4.8 indicates that sales are predicted to increase by $4.8 billion/year.b. Intepret the slope, b₁. Which statement below is the interpretation of the slope?A. The slope b₁ = 4.8 indicates that sales are predicted to increase by $4.8 billion/year.B. The slope b₁ = 4.8 reflects the predicted net sales in 1963.C. The slope b₁ = 1.3 reflects the predicted net sales in 1963.D. The slope b₁ = 1.3 indicates that sales are predicted to increase by $1.3 billion/year.c. What is the fitted trend value for the ninth year?$16.5 billion(Simplify your answer.)

Given Yi^ = 4.8 + 1.3Xi As per the student's request, I am providing the solution to the (c)…

The linear trend forecasting equation for an annual time series containing 45 values (from 1963 to 2007) on net sales (in billions of dollars) is shown below. Complete (a) through (e) below. ₁ =4.8+1.3X, a. Intepret the Y-intercept, bo. Which statement below is the interpretation of the Y-intercept? OA. The Y-intercept bo = 1.3 reflects the predicted net sales in 1963. OB. The Y-intercept bo=1.3 indicates that sales are predicted to increase by $1.3 billion/year. C. The Y-intercept bo = 4.8 reflects the predicted net sales in 1963. OD. The Y-intercept bo = 4.8 indicates that sales are predicted to increase by $4.8 billion/year. b. Intepret the slope, b₁.
