Using a t-distribution, he \u00a0generates a two-sided confidence interval (CI) of 83 +\/- 1.984217 \u00a0*5\/sqrt(100). The 95% CI is then (82.007, 83.992). If repeated intervals \u00a0were conducted identically, 95% should contain the population mean. The \u00a0two-sided hypothesis test can be formulated and tested just with this \u00a0interval. Ho: Mu = 87, Ha: Mu&lt;&gt;87. Alpha = .05. If he assumes \u00a0normality and that population standard deviation is unknown, he selects \u00a0the t-distribution. After constructing a 95% CI, he notes that 87 is not \u00a0in the interval, so he can reject the null hypothesis that the mean \u00a0satisfaction rates are 87. In fact, he has an evidence-based analysis to \u00a0suggest that the mean satisfaction rates are not equal to (less than) \u00a087.<\/em><\/p>\n<p>For this Discussion, review the resources for this week, and consider \u00a0how a CI might be used to support hypothesis testing in a healthcare \u00a0scenario.<\/p>\n<h5>By Day 3<\/h5>\n<p><strong>Post<\/strong> a description of a healthcare scenario where a \u00a0CI might be used, and then complete a fictitious two-sided hypothesis \u00a0test using a CI and fictitious data.<\/p>\n<p>\u00a0<\/p>\n<blockquote><p>Albright, \u00a0S.
