Answer 2

Option D, It is neither accurate nor precise

Step-by-step explanation:

To determine whether a given value is precise or not –

The value 27 must not deviate by a large difference from a given set of data, otherwise it will be not precise

The average of given data set is

`(19+31+22+28+24)/(5) \\= 24.8`

So the deviation of 27 from the mean value is

`24.8-27\\=-2.2\\`

Hence, the given value is not precise

Accuracy is something which determine whether the obtained value is equal to the predetermined values. It is measured in terms of percent error.

Here in this case the value 27 is very different from the numbers in the data set.

Hence, option D is correct
