Q 1.10: A question "Is it preferable for a modern woman to wear make up every day?" was published in three magazines: one for young mothers, another for men, and the third for elderly people. Answers "Yes" scored 28%,
65%, and 35%, respectively. Why do these answers vary? Can the samples be generalized to the population of all
people in the world?
А)
These answers vary because the audience of the three magazines differs sufficiently, so the samples
containing people of the three audiences cannot be generalized to the population since the readers of
a magazine may not be a sample from the population.
B
These answers vary because the samples of all three magazines were not random. If the samples were
truly random, they could be generalized to the population.
These answers vary because the size of the samples was not restricted, and, perhaps, it differs for the
three groups of the respondents, so the samples cannot be generalized to the population.
D
These answers vary because the audience of the three magazines differs sufficiently, but the samples
containing people of the three audiences can be generalized to the population.
