A marketing manager is analyzing the sales figures of two competing products, Product A and Product B, over six months. The following data represents the total units sold each month:
Product A: June: 120, July: 150, August: 180, September: 160, October: 200, November: 240
Product B: June: 140, July: 170, August: 150, September: 200, October: 250, November: 220
Based on this data, determine which product had a greater average monthly sales figure over the period and by how much.
