## 最终结论
```python
def is_majority(arr, n, candidate):
    count = 0
    for num in arr:
        if num == candidate:
            count += 1
    return count > n // 2

# Test cases
assert is_majority([1, 2, 3, 3, 3, 3, 10], 7, 3) == True
assert is_majority([1, 1, 2, 4, 4, 4, 6, 6], 8, 4) == False
assert is_majority([1, 1, 1, 2, 2], 5, 1) == True
