Answer 1

Correct Answer - Option 2 : 36.13

Formula used :

Mean = sum of all the values/Number of values 

Calculations :

Sum of values = 9 + 12 + 14 + 15 + 16 + 17 + 21 + 45 + 64 + 34 + 54 + 66 + 23 + 65 + 87 

⇒ 542

Total values = 15 

Mean = 542/15 

⇒ 36.13 

∴ 36.13 will be the Mean of the given set
