Answer:


Explanation:
Solving (a): P(Joe)
To get this probability, we simply add up the items in the column named Joe.
These items are:
Joe: 34 and 70
And the total is:


The overall population of the system is:

So:


Solving (a): P(Joe and North Side)
To get this probability, we simply get the intersecting element of Joe column and North Side row.
From the table, the intersecting element is:
Joe and North Side: 70
The overall population of the system is:

Answer:
The correct option is;
D) Observational study
Explanation:

In the question, the researcher observes to determine the the number of people that run a light through pre recorded traffic video providing a physical restraint which makes it an observational study.
