Select all of the statements that are true for representative samples.
Select all of the statements that are true for representative samples. Simple random sampling is used to collect the sample. The size of the sample is greater than 30 to ensure greater accuracy in the results of the study. Every member of the population has an equal probability of being selected to participate in the study. The relevant characteristics of the population are included accurately in the members of the sample. The intended results of the study are unbiased and can be generalized to the...
