Confidence Z-value z-Value Level (Table) (Еxcel) Excel Formula 95% (0.95) =ABS(NORM.S.INV(0.025)) 3. Calculate the three confidence intervals using a 95% confidence level. You may do this by hand or with Excel. You must show your work. Your answer must include the Point Estimate, Margin of Error (MoE), Lower Confidence Limit (LCL), and the Upper Confidence Limit (UCL). Excel does not have a Confidence Interval function for proportions. (Show your work. Use Excel.) p(1 - p) p±z n 4. What do the confidence intervals you constructed tell you? 5. What would happen to the confidence intervals if you changed the level of confidence? 6. What would happen to the confidence interval if you increase the sample size?
