Determine whether the sampling method described below appears to be sound or is flawed. in a survey of 714 subjects, each was asked how often he or she read a book. read a book. the survey subjects were internet users who responded to a question that was posted on a news website.
a) it is flawed because it is a census
b) it is flawed because it is not statistically significant.
c) it appears to be sound because the data are not biased in anyway.
d) it is flawed because it is a voluntary response sample.

Option D) It is flawed because it is a voluntary response sample.

Step-by-step explanation:

We are given the following information in the question:

The subjects of the survey were internet users who responded to a question that was posted on a news website.

A total of 714 subjects responded to this question, answering the question, how often he or she read a book.

Option D) It is flawed because it is a voluntary response sample.

Voluntary response sample:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
