Question

Answer

Trend Equation for Annual Sale of Production:

Predicting Annual Sales for Year 1992:

To predict the annual sales for year 1992, we need to substitute the value of x as 0 in the trend equation, because the year 1992 is taken as the origin year.

Explanation:

Here, y represents the annual sale of production and x represents the number of years since the origin year.

Since the origin year is taken as the year 1992, the value of x for the year 1992 is 0.

To predict the annual sales for the year 1992, we need to substitute the value of x as 0 in the trend equation.
