2. histogram graph based on the frequency distribution
3. summary paragraph discussing observations and conclusions

Answer 1

Solution:-

Year	Frequency	Relative Frequency	Cumulative Frequency	Cumulative relative Frequency
2015	995	995/3943= 0.252346	995	0.252346
2016	963	963/3943= 0.24423	995+963=1958	0.252346+0.24423=0.496576
2017	987	987/3943= 0.250317	1958+987=2945	0.496576+0.250317=0.746893
2018	998	998/3943= 0.253107	2945+998=3943	0.746893+0.253107=1
Total	3943	1

Histogram:-

from the graph we can conclude that the nationwide officers involved shootings resulting in fatalities distribution are distributed Uniformly.
