It's B) A straight line can be drawn through all the points and the line passes through the point (0,0)
This is because in the problem it says that the points are paired and proportional. For example, say you're given the point (3,6). To make this a proportional relationship, you'd have another point in the third quadrant: (-3,-6). When you draw a line from one of these points to the other, it passes through the origin.
Answer:
B.
Step-by-step explanation:
There are 20C4 = 4845 ways to take a sample of 4 from 20.
For choices A and C, the mean will be over-estimated if 3 of the 4 samples are of the higher value. There are (10C3)×10 = 1200 samples that will cause the mean to be over-estimated.
For choice D, every sample will correctly estimate the mean, so there are 0 samples that will cause the mean to be over-estimated.
For choice B, any sample that contains all 2s will over-estimate the mean. There are 19C4 = 3876 such samples.
Of the data sets listed, a sample of 4 from data set B is most likely to be one of the samples that will over-estimate the mean.
