Asimple random sample of n measurements from a population is a subset of the population selected in a manner such that which of the following is/are true? (select all that apply.)

a. sample of size n from the population has an equal chance of being selected.
b. every member of the population has an equal chance of being included in the sample.
c. the simplest method of selection is used to create a representative sample.
d. each subset of the population has an equal chance of being included in the sample.
e. every sample of size n from the population has a proportionally weighted chance of being selected.

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.                                            

Step-by-step explanation:

Simple random sampling:

a) sample of size n from the population has an equal chance of being selected.

b) Every member of the population has an equal chance of being included in the sample.

The statement is false.

There is no pattern or technique used for selection. The selection is purely random.

The statement is false.

Each object of the population has an equal chance of being included in the sample. and not each subset.

The given statement is false.
