Confidence Intervals and Sample Size The precision of a confidence interval can be increased by increasing the sample size. Discuss whether it is possible to define an ideal or optimal sample size. If yes, how should it be determined? If not, why not? Embed course material concepts, principles, and theories (require supporting citations) along with at least one scholarly, peer-reviewed reference in supporting your answer. Keep in mind that these scholarly references can be found in the Saudi Electronic Library by conducting an advanced search specific to scholarly references.
