Just KNIME It _​ Challenge 040

Z-test determine whether two population means are different, when the variances are known and the sample size is large. It calculates Z scores to input critical values in order to make a decision about whether a Null Hypothesis is still valid or not.
This component covers optionallity for both: Rejection Region and Proportion Testing calculation.

Just KNIME It! - Challenge 40: Season FinaleZ-score Hypothesis Testing (one tailed Regection Region or Proportion)This component performs z test on a dashboard's manually input data for Rejection Region, or on Proportion testing. It checks if the means of two large samples are different or not when the population variance is known.The dashboard displays the z test results in three different views: 1.- Null hypothesis rejection True/False matrix.2.- Py supported H0 vs H1 PDF chart (z-score scale)3.- Numeric results summary.Uses: Besides to illlustrate z-score statistical theory; this component's dashboard views can be used to plan and test needed sampling size, aiming to satisfy significance condition.
