Consider this population data set:4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12. The values 11, 31, 22, and 12 constitute a ra

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>
According to the given graph, the variables does not show a proportional relationship because they points do not form an straight line. Remember that the proportional relationship is represents by a straight line whcih passes through the origin.
<h2>Therefore, the hours and the height of snow do not show a proportional relationship.</h2>

Explanation: formula of a circle
A= pi r ^2
any of the 34 cars can finish first
any of the remaining 33 cars can finish second
any of the remaining 32 cars can finish third
Thus, the top 3 finishes can be done in (34)(33)(32) = 35904 ways
