Question

Three students found the mean of the data set given. Their work is shown below. Choose the student who correctly found the mean. 10, 10, 13, 14, 16, 19, 23 Naeem's Work. StartFraction 10 10 13 14 16 19 23 Over 7 EndFraction = StartFraction 105 Over 7 EndFraction = 15 Preston's Work. StartFraction 10 13 14 16 19 23 Over 6 EndFraction = StartFraction 95 Over 6 EndFraction = 15. 8 Calida's Work. StartFraction 10 23 Over 2 EndFraction = StartFraction 33 Over 2 EndFraction = 16. 5.

Answer 1

Hey there!

Formula:

SUM of all numbers / TOTAL numbers you have in your data plot

EQUATION:

(10 + 10 + 13 + 14 + 16 + 19 + 23) / 7

10 + 10 + 13 + 14 + 16 + 19 + 23
= 20 + 13 + 14 + 16 + 19 + 23

= 33 + 14 + 16 + 19 + 23

= 47 + 16 + 19 + 23

= 63 + 19 + 23

= 82 + 23

= 105

105 / 7

= 15

So, therefore the answer is: Naeem's Work. Start fraction 10, 10, 13, 14, 16, 19, 23 Over 7 end fraction = StartFraction 105 Over 7 end fraction = 15 (Option A.)

Good luck on your assignment & enjoy your day!
