Module 5, Homework 2
1. You are looking at reckless driving cases. You chose 300 cases to determine whether there is
a difference between which county arrested the suspect and if a conviction was made. *Not
actual numbers.* (Make sure to show your work.) For questions b through d, your final
answer will have a decimal point. Use two decimal places, i.e. .00
Conviction
Jo Daviess County (North)
McDonough County (Middle)
Sangamon County (Middle)
Dupage County (North)
Alexander County (South)

a) What is the dependent variable being studied? (1 point)
b) What is the probability there will be no conviction in an arrest made in a northern
county? (1 point)
c) What is the probability of a conviction being made? (1 point)
d) What is the probability of a conviction in Sangamon County? (1 point)
2. If the probability that an officer makes an arrest on a traffic stop is 0.18, construct a
probability distribution for the probability of an officer arresting 0 to 5 drivers when 5 traffic
stops are conducted by the officer.. (Each space is worth 0.5 points for a total of 12 points.)
For this table, you will round to the nearest ten-thousandths (four decimal places). Show your
work. Review Table 6.3 on p. 146 in your textbook for help.
