Answer

Explanation:

Step1: Calculate variation for Sample 1

Variation is the difference between predicted and actual mean. For Sample 1, it is $34 - 28=6$.

Step2: Calculate variation for Sample 2

For Sample 2, the variation is $|15 - 28| = 13$.

Step3: Calculate variation for Sample 3

For Sample 3, the variation is $29 - 28 = 1$.

Answer:

Sample 1: 6 Sample 2: 13 Sample 3: 1
