Nonparametric test statistics frequently consti- tute estimates of important parameters: the sign test statistic estimates the probability of a positive response; the Wilcoxon two sample test statistic (rather, a known function of it) estimates the probability that an individual selected at random from one population will have a larger score than an indi- vidual selected at random from a

Non-parametric methods still use traditional statistical hypothesis testing; the Mann-Whitney U test involved a null hypothesis that stated that the distribution of the Apgar scores at five minutes was similar for each of the treatment groups in the population. The Mann-Whitney U test was based on ranking the sample values of the Apgar scores regardless of treatment group. Under the null
