Study the following line graph and answer the questions based on it.Number of…

Concept: The average (mean) of a set of values equals the sum of all the values divided by the number of values: Average = (Sum of all observations) / (Number of observations). When the data is presented as a line graph, first read every plotted value accurately before applying this formula.

Applying it to this graph:

1. Read Company X's (blue line) value for each year from the graph: 1997 = 119, 1998 = 99, 1999 = 141, 2000 = 78, 2001 = 120, 2002 = 159 (all figures in thousands).

2. Add all six yearly values: 119 + 99 + 141 + 78 + 120 + 159 = 716 (in thousands).

3. There are 6 years in the given period (1997 to 2002), so divide the total by 6: 716 ÷ 6 = 119.3333…

4. Convert back to actual vehicles and round to the nearest integer: 119.3333… thousand = 119,333.33…, which rounds to 119333.

Cross-check: Grouping the six values into three pairs and adding each pair gives 119 + 120 = 239, 99 + 141 = 240, and 78 + 159 = 237; these three partial sums add to 716, the same total obtained above, confirming the addition is correct.

So the average number of vehicles manufactured by Company X over 1997–2002, rounded to the nearest integer, is 119333.
