Atmospheric Aerosols and Visibility Study

An environmental research agency investigated the relationship between the concentration of fine particulate matter ( $PM_{2.5}$ ) and horizontal visibility in an industrial region. They gathered paired measurements from 8 distinct monitoring stations on a specific afternoon:

$PM_{2.5}$ concentration ( $P$ , in micrograms per cubic metre): The concentration of fine inhalable particles with diameters 2.5 micrometres and smaller.
Visibility ( $V$ , in kilometres): The maximum horizontal distance at which an observer can clearly discern prominent objects.

Table 1: $PM_{2.5}$ concentration and visibility readings

Monitoring Station	$PM_{2.5}$ concentration ( $P$ )	Visibility ( $V$ )
A	12.4	15.2
B	35.8	8.1
C	8.5	18.0
D	55.2	3.5
E	22.1	11.4
F	72.0	1.8
G	15.6	14.0
H	44.3	5.2
