Difficulty: Easy
Correct Answer: 12
Explanation:
Introduction / Context:
Uniform scaling of every data point scales the average by the same factor. Doubling every bouquet's count doubles the mean as well.
Given Data / Assumptions:
Concept / Approach:
If each value is multiplied by k, the average is multiplied by k. Here k = 2.
Step-by-Step Solution:
Verification / Alternative check:
Consider three bouquets with counts 5, 6, 7 (average 6). Doubling gives 10, 12, 14 (average 12). Pattern generalizes to any data set.
Why Other Options Are Wrong:
Common Pitfalls:
Confusing doubling with adding a fixed number; multiplying is required here.
