A U.S. Senate Judiciary Committee report showed the number ofhomicides in each state. In Indiana, Ohio, and Kentucky, the numberof homicides was, respectively, 380, 760, and 260. Suppose astratified random sample with the following results was taken tolearn more about the victims and the cause of death.
| Stratum | Sample Size | Shootings | Beatings | Urban Victims | |
| Indiana | 30 | 10 | 9 | 21 | 380 |
| Ohio | 45 | 19 | 12 | 34 | 760 |
| Kentucky | 25 | 7 | 11 | 15 | 260 |
a. Develop an approximate 95% confidenceinterval for the proportion of shooting deaths in Indiana (to 4decimals).
b. Develop an estimate for the total number ofshooting deaths in Ohio (to whole number).
c. Develop an approximate 95% confidenceinterval for the proportion of shooting deaths in Ohio (to 4decimals).
d. Develop an approximate 95% confidenceinterval for the proportion of shooting deaths across all threestates (to 4 decimals).
