a) This sampling approach will be biased because peo-

ple might dial the number incorrectly, and therefore
not everyone will be correctly represented.
b) This sampling approach will be biased because the

ple will not be representative of the population.
c) This sampling approach will be unbiased because
people can call in with either opinion, therefore the
sample will be representative of the population.
d) This sampling approach will be unbiased because
the station doesn’t know who will call in, making it a
random sample.
e) It is impossible to tell whether this sampling
approach will be biased or not because the station
