Answer:
A) Refer attached fig. or pareto chart
Step-by-step explanation:
Given data
Rivers Bann Blackwater Erne Shannon Barrow
Spearheads(fi) 19 8 15 33 14
a)
Pareto charts are those charts who has both bars and lines. bars are shown in descending order and the cumulative total is represented by the line.
b) Circle graph
Circle graph is also known as pie chart
In this chart we divided into circle in to different segments according to formula.
Total frequency of spreads in = 19+8+15+33+14=90
i) Bann
fi =19
percentage = [tex]\frac{19}{90}\times100 = 21.35[/tex]%
Segment size = 21.35% × 360 = 77°
ii) Black water
fi = 8
percentage = [tex]\frac{8}{90} \times 100[/tex] = 8.99%
Segment size = 8.99% × 360 = 32°
iii) Erne
fi = 15
percentage = [tex]\frac{15}{90} \times 100[/tex] = 16.85%
Segment size = 16.85% × 360 = 61°
iv) Shannon
fi = 33
percentage = [tex]\frac{33}{90}\times100[/tex] = 37.08%
Segment size = 37.08% × 360 = 133°
iv) Barrow
fi = 14
percentage = [tex]\frac{14}{90} \times100[/tex] = 15.73%
Segment size = 15.73% × 360 = 57°
