Answer #1

Target answer is 2.4

So, calculated value will be said to be precise if the caluculated average value will be completely equal to the target data.

For the given case Data for 3 observations are : 2.9, 3.1, 3.0

So, the average value will be = ( 2.9+3.1+ 3.0) ÷ 3 = 3.0

So, the given date is accurate average but not precise

Therefore, the right option is (b).
