In a binomial experiment with n trials and probability of success p, if ________, the binomial random variable X is approximately normal with μx= and σx = __________ .
Step 1 of 5) In a binomial experiment with n trials and probability of success p, if the binomial random variable X is approximately normal with μx= and σx = . We therefore tested the linear relation between the two variables by determining whether the slope coefficient, b1, was significantly different from 0. But this test required that the residuals be normally distributed. In this section, we introduce the nonparametric Spearman’s rank-correlation test, which can be used to test the hypothesis that two variables are associated. Perform Spearman’s Rank-Correlation Test. Definition The Spearman’s Rank-Correlation Test is a nonparametric procedure used to test hypotheses regarding the association between two variables. When performing the rank-correlation test, we test the hypothesis that an association exists between the two variables. There are three ways to structure the hypothesis test.
