Greetings from Brasil...

Observing the arrangement of the points, we notice that a line is the closest to this grouping. Tracing the line between the points (blue line) - refer to attached

We note that zero people at home will not spend any amount, so the first point will be (0; 0).

After the straight line and the alternatives of the question, we can say that for 8 people there is a cost of

(each vertical division (Y-axis) is equivalent to $20)

two data sets with the same median will not have the same varaibility

step-by-step explanation:

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
