Step-by-step explanation:
The question asks for you to talk about precision and accuracy, precision is defined by how close the results are when repeated so the three results are precise. The difference in weight between the three measurements is within .3g of each other so this proves your precision is good.
However, the accuracy is bad because the results and the actual weight of the apple are far away, the mean distance can be calculated via adding up all three measurements and dividing by three:
167 + 166.9 + 167.2 = 501.1
501.1 ÷ 3 = 167.03
172 - 167.03 = 4.97
So the mean distance is 4.97g away from the actual weight of the apple, this shows that the results are not accurate.
Hope this helps!
