To accurately calculate the average deviation from the mean number of goals per game for soccer team B, you would first need to determine the mean of the plotted values on the number line, then calculate the absolute deviations from that mean for each value, and finally average those deviations.
However, without the specific goals per game values provided in the image, I can't calculate the average deviation directly.
Please provide the exact values plotted on the number line, and I can guide you through the calculations. Alternatively, choose one of the provided options based on your understanding of the calculated values.
