The 2017 version of the Broselow Tape incorporates revised length weight zones based on the most recent National Health and Nutrition Examination Survey (NHANES) data set. *If the healthcare provider incorporates a visual estimate of body habitus into the prediction, the accuracy of the estimate of actual patient weight is improved as confirmed in multiple studies.
Confidence intervals provide more information than point estimates. Confidence intervals for means are intervals constructed using a procedure (presented in the next section) that will contain the population mean a specified proportion of the time, typically either 95% or 99% of the time.
Based on the sample provided, the confidence interval for the population mean is 98.08 o ÂµÂµÂµÂµ o. The interval is the same here as in Section 7-2, but in some other cases, the difference would be much greater. x â ÂµÂµÂµÂµ Copyright Â© 2007 Pearson Education, Inc Publishing as Pearson Addison-Wesley.
