Step-by-step explanation:

The alternating current (AC) breakdown voltage of an insulating liquid indicates its dielectric strength. An article gave the accompanying sample observations on breakdown voltage (kV) of a particular circuit under certain conditions. 62 51 53 58 42 54 56 61 59 64 51 53 64 62 50 68 54 55 57 50 55 50 56 55 46 56 54 55 53 47 48 56 58 48 63 58 57 56 54 59 54 52 50 55 60 51 56 59 Construct a boxplot of the data.

The boxplot is a method to represent a series of numerical data through their quartiles. In this way, the box diagram shows at a glance the median and quartiles of the data.

C. Makita helped her 4 younger brothers with their homework.

Step-by-step explanation:

Extraneous information is the information which is not needed to solve the question. In this Makita helped 4 brothers is extraneous information because it does not solve the question asked. The question asked is how much did she earn? For this we need to know that she worked a total of 3 hours. Her aunt paid her $ 10.00 per hour. But it has nothing to do with her brothers.

And ofcourse the question asked how much did she earn cannot be extraneous information itself.

Option C shows the extraneous information.

Option A, B and D are required in the question to answer.
