A group of students got the following scores in an achievement test: 9,12,15,18, 21, and 24. Consider samples of size 3 that can be drawn from this population. A. Determine and list all possible samples and the corresponding sample means. SAMPLE MEANS RANDOM SAMPLES​

Answer 1

9, 12, 15; mean = 12

9, 12, 18; mean = 13

9, 12, 21; mean = 14

9, 12, 24; mean = 15

9, 15, 18; mean = 14

9, 15, 21; mean = 15

9, 15, 24; mean = 16

9, 18, 21; mean = 16

9, 18, 24; mean = 17

9, 21, 24; mean = 18

12, 15, 18; mean = 15

12, 15, 21; mean = 16

12, 15, 24; mean = 17

12, 18, 21; mean = 17

12, 18, 24; mean = 18

12, 21, 24; mean = 19

15, 18, 21; mean = 18

15, 18, 24; mean = 19

15, 21, 24; mean = 20

18, 21, 24; mean = 21
