Merging Data Tables
1. Two classes, Class A and Class B, took the same math test. The scores for Class A are: 78, 85, 92, 70, 88. The scores for Class B are: 82, 75, 90, 85, 78, 95. Merge these two datasets into a single ordered list.
2. A survey recorded the favorite fruits of students in two different grades. Grade 7 results: Apple (12), Banana (8), Orange (5). Grade 8 results: Apple (10), Banana (15), Grapes (7). Combine this data to show the total number of students who prefer each fruit across both grades.
