Practice Problem 4: For the data below (from the beginning of the section), find the range, σ 2
and σ (population), and s
2 and s (sample), and note that they are larger than the corresponding
values found in Example 6.
0 5 10 10 15 20

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

it would rotate about 180 degrees.

the correct answer would be the third option

they r 125, and 216

so the sequence goes 1,8,27,64,125,216
