Question

A researcher stands on a street corner and surveys people who pass by about their opinion on contraception. because the researcher interviewed an equal number of men and women, the researcher's study uses random sampling.

Answer 1

That statement is False.
If the researcher is  using random sampling, All subjects that chosen for the study had equal responsibility of being chosen
When the researcher determines that the amount of female and male subjects, must be the same,  the research no longer has the equal opportunity for all the test subjects to be chosen.
