In addition to deriving our confidence interval estimates, we investigate other uses of the confidence interval. Particularly, this includes using confidence intervals as stand-ins for two-sided hypothesis tests for means. This flexibility mirrors our results found in our confidence intervals for a ...
Each sample includes at least 10 successes and 10 failures.The Variability of the Difference Between ProportionsTo construct a confidence interval for the difference between two sample proportions, we need to know about the sampling distribution of the difference. Specifically, we need to know how to...
Due to this reason, Kateri and Balakrishnan [32] proposed two different methods to construct confidence intervals, namely; (i) the asymptotic confidence interval when the sample size is large and (ii) the bootstrap confidence interval when the sample size is small or moderate. When the sample...
1. Confidence intervals provide all the information that a test of statistical significance provides and more. If, at the 95 percent confidence level, a confidence interval for an effect includes 0 then the test of significance would also indicate that the sample estimate was not significantly diff...
