Answer:

3.5

Step-by-step explanation:

Find the Mean of the Population Data Set

4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12 = 186

186 ÷ 12 = 15.5

Find the Mean of the Sample Data Set

11 + 31 + 22 + 12 = 76

76 ÷ 4 = 19

Subtract

19 - 15.5 = 3.5

Answer: <em>The sample mean is more than the population mean by 3.5</em>
