Set \(C\) is \(18\), \(19\), \(20\), \(21\), \(22\) and set \(D\) is \(5\), \(12\), \(20\), \(28\), \(35\). Which statement about them is correct?
Set \(D\) has the higher mean and the greater range.
The two sets have the same mean, but \(D\) is far more spread out than \(C\).
Set \(C\) is more spread out, because its values are closer together.
The two sets are identical, because their means are equal.
