Answer 1

Mean = The sum of all of the data divided by the total number of data values in a data set.

n = 10

country	Emissions	Per capita Emissions
1	6049435	5.91
2	5020170	1.25
3	1524993	2.89
4	1342962	0.34
5	1257963	2.69
6	806767	2.68
7	639403	5.46
8	587261	2.67
9	465643	2.64
10	449948	2.12
Sum	18144545	28.65

Mean = µ = ∑Emissions / n

µ = 18144545 /10 = 1814454.5

b) The emission per capita is better because it adjusts emissions for population size. so the answer is B

Total emissions are not considering the population size which is a big drawback of it.

c) Mean = µ = ∑Emissions per capita / n

Mean, µ = 28.65/10 = 2.865

Median = The numeric value separating the higher half of the sample data from the lower half.

= ( 5th term + 6th term ) / 2

= ( 2.67 + 2.68 ) / 2 = 2.675

d) Since environmentalist wants to prove that emissions are high so he will use mean because mean is higher than the median.

Mean is 2.865 and the median is 2.675.

So answer is A
