The best way to solve this problem is by plugging in each answer choice for both equations and seeing which one works. You can already see that choice A doesn't work because -1 is not greater than or equal to 4. That means you just need to test choices B and C!
Choice B (4, -2)
2 is not greater than or equal to 6, so choice B doesn't work.
Choice C (4, 2)
Since 6 is equal to 6 and 4 is equal to 4, choice C works!

Answer: C) (4, 2)
Choice B (4, -2)
2 is not greater than or equal to 6, so choice B doesn't work.
Choice C (4, 2)
Since 6 is equal to 6 and 4 is equal to 4, choice C works!

Answer: C) (4, 2)
Answer:
(a) 12.87; 14; 18; (b) median
Step-by-step explanation:
(a) Statistics
(i) Mean
The mean is the sum of all the data points divided by the number of points.
(ii) Median
The median is the middle value in your list of observations.
0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20
Median = 14
(iii) Mode
The mode is the value that appears most often in your list of observations.
0, 2, 3, 12, 12, 13, 14, 14, 15, 15, 18, 18, 18, 19, 20
Mode = 18
(b) Most representative measure
The mean is dragged down by three low values. The median is the measure that is most representative of the data.
The histogram below shows the distribution of your data.
