Answer 2

The correct option is B, which is statement IV.

Let us look at each of the statement provided to us:

I) Randomization allows each member of the population to have an equal probability of being selected for the sample population.

This is a true statement because in randomization sample is picked up randomly among the number of options available.

II)  Randomization helps avoid bias.

This is a true statement because in randomization sample is picked up randomly among the number of options available which helps avoiding bias sampling.

III)  Randomization protects against unknown factors.

This is a true statement, because randomization helps to know the unknown factors that can later on create a problem, it help us to know the unknown possible factors that can affect the project later on.

IV)  Randomization can be replaced by accurately matching the sample to the population.

This is a false statement, As if we accurately match the sample to the population still there may be some biased sample that may be selected due to some human error.

V)  Randomization allows one to draw inferences about a population through a sample.

This is a true statement, because randomization helps to know the most of the possible options that a population can choose.

Hence, the correct option is B, which is statement IV.
