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>
