(e) What will happen to the error bound and confidence interval if 6 community colleges were surveyed? Why? The error bound and confidence interval will both increase since decreasing the sample size decreases variability in the sample. The error bound and confidence interval will both increase since decreasing the sample size increases O variability in the sample.
