To find: The correct option for the given situation.
The correct option is (C).
Given information:
The situation is “A doctor studies the effects of nicotine on a person’s health by monitoring the health of 100 randomly selected smokers and 100 randomly selected nonsmokers.”
Explanation:
Experiment: A treatment that is done on individuals in order to collect data on their response is known as the experiment.
Observational study: An observation on individuals and measuring variables without controlling the individuals or their environment.
Sample survey: A random sample is selected to be surveyed from the population studied.
In the given situation, a doctor selected random group of smokers and nonsmokers from the population to monitor the effect of nicotine on a person’s health. So, this situation is sample survey.
Therefore, the correct option is (C).

Assume that there are a total of 900 users at these three websites. This gives us the following system of linear equations: x1 = x2 + 1x3 x2 = x1 + x3 x3 = x2 = 900 x1 + x2 + x3 = (a) Put this system into a standard form (with all variables on the left side and with the constants on the right), and convert that system into an augmented matrix, and then...
