A Researcher E-Mails Links to an Online Survey About Multi-Tasking

A researcher e-mails links to an online survey about multi-tasking and overcommittedness both on and off the job, as they relate to quality of life, to a random selection of 20,000 RNs in all 50 states; this represents about 1% of the population of RNs. The return rate on the tool is 5%. The goal of this sampling method is to obtain a representative sample. Choose the correct statement(s) relative to the sample's representativeness.

A) Since the topic has to do with multi-tasking and overcommittedness, it is likely that the results will be skewed, since RNs who are vastly overcommitted will not complete the survey.
B) The sample is automatically representative if randomly selected names were used for the survey e-mailing.c.If the e-mailed subset of the population was randomly selected and the return meets the number required by power analysis, the return is representative.
D) Subjects whose perceived quality of life is either very high or very low may be more inclined to participate, since they have an interest in finding more out about this relationship.
E) If the 1000 subjects who return the survey constitute an insufficient number to demonstrate statistical significance, this means that the sample was not truly representative.
F) The sample is so huge, it would certainly be representative of the entire population.
