1. The problem provides weekly sales data for Branch A and Branch B over five weeks. 2. To analyze, we can calculate: - The average (mean) sales for each branch - The range of sales 3. For Branch A, sales are: $$102, 106, 105, 115, 112$$ Calculate the mean: $$\text{Mean}_A = \frac{102 + 106 + 105 + 115 + 112}{5} = \frac{540}{5} = 108.\$$ Calculate the range: $$\text{Range}_A = 115 - 102 = 13.\$$ 4. For Branch B, sales are: $$100, 116, 87, 102, 100$$ Calculate the mean: $$\text{Mean}_B = \frac{100 + 116 + 87 + 102 + 100}{5} = \frac{505}{5} = 101.\$$ Calculate the range: $$\text{Range}_B = 116 - 87 = 29.\$$ 5. Summary: - Branch A average sales per week is 108 with a range of 13. - Branch B average sales per week is 101 with a range of 29. This shows Branch A has higher and more consistent weekly sales compared to Branch B.
