Which data sets are precise based on a correct value of 42? check all that apply. set 1: 41, 23, 42, 19 set 2: 24, 23, 25, 24 set 3: 41, 42, 41, 43 set 4: 42, 15, 42, 98 set 5: 89, 13, 17, 25

set 1: 42,42,42

Explanation:

Set 3: 41, 42, 41, 43

Explanation:

Set 1: 41, 23, 42, 19

Set 2: 24, 23, 25, 24

Set 3: 41, 42, 41, 43

Set 4: 42, 15, 42, 98    

Set 5: 89, 13, 17, 25

The average value of set 1, d₁ = 31.25

The average value of set 2, d₂ = 24

The average value of set 3, d₃ = 41.75

The average value of set 4, d₄ = 49.25

The average value of set 5, d₅ = 36

We need to find the data that is precise based on a correct value of 42. Data 3 is more precise than any other. So, the correct set that is precise of 42 is set 3.
