Answer 2

The approximate total weight of the grapefruits, using the clustering estimation technique is B. 35 ounces.

Explanation:

We notice that the weights of the grapefruits given are slightly down or above 7, then we will use 7 as our cluster for the estimation, as follows:

Weights

7.47 ⇒ 7

7.23 ⇒ 7

6.46 ⇒ 7

7.48 ⇒ 7

6.81 ⇒ 7

Now we can add up 7 + 7 + 7 + 7 + 7 for the weights of the grapefruits and the approximate total weight is B. 35 ounces.
