Section Review
SUMMARY
Here, the focus was on confidence intervals and sample sizes. We considered
large sample confidence intervals for a population proportion and mean, and
for the difference between two population proportions and means. We also
considered formulas for finding sample sizes under different conditions. We
computed various confidence interval estimates for these parameters. The
workbook used for these computations can compute from 90% to 99%
confidence. These concepts were presented through
