Margin of error - Inference App - DrD - 07-19-2019 02:15 PM
Given: With a confidence level of 95%, out of 280 trials, there were 123 successes. What is the margin of error? Inference App [Symb] Method: Confidence interval Type: Z-Int: 1 pi [Num] x:123 n:280 c:0.95 [Plot] NOTE: Confidence interval is shown, the margin of error is not shown, typically reported as the center value ± margin of error. Can this be shown on the plot somehow? -Dale- [attachment=7486] |
