Answer:
Step-by-step explanation:
a) Pareto charts are column charts showing frequency for each category, plus a line chart showing the cummulative values for all categories. They usually start with the most frequent category first, which is general torts in your case.so the first column will be
General torts: column at a height of 191, line point at 191.
next is,
Contracts: column at a height of 107, line point at 191 + 107 = 298.
next is,
Asbestos liability: column at a height of 49, line point at 191 + 107 + 49 = 347
next is,
Other product liability: column at a height of 38, line point at 191 + 107 + 49 + 38 = 385
next is,
All other: column at a height of 21, line point at 191 + 107 + 49 + 38 + 21 = 406
b) A pie chart is a circle divided into webges based on the portion that each category contributes to the total. In your case, the total number of suits is:
107 + 191 + 49 + 38 + 21 = 406
so the first category , Contracts represents 107 / 406 of the total cases,
107 / 406 = 26.4%
you can convert this to an angle of the wedge by applying the same percentage to the number of degrees in a circle, 3600.
26.4% * 3600 = 95.00.
so the wedge for contract would be labeled 26.4%, and the wedge makes an angle of 95.00.
Like wise,
for General torts, the wedge would be labeled as 191 / 406 = 47.0%
and the wedge makes an angle of 47.0% * 3600 = 169.20.
for Asbestos liability, the wedge would be labeled as 49 / 406 = 12.1%
and the wedge makes an angle of 12.1% * 3600 = 43.60.
for Other product liability, the wedge would be labeled as 38 / 406 = 9.4%
and the wedge makes an angle of 9.4% * 3600 = 33.80.
for All other, the wedge would be labeled as 21 / 406 = 5.2%
and the wedge makes an angle of 5.2% * 3600 = 18.70.
