A survey dataset contains cholesterol level (mg/dL) for ?1=10
female and ?2=12 male adults.
female:218,164,217,215,180,188,245,241,318,238
male:167,149,218,133,154,221,148,220,339,237,205,197 Use the
Wilcoxon rank sum test to compare the distributions of cholesterol
level for female and male adults. Compute the sum of ranks for each
sample with ties, the mean of the test statistic, the standard
deviation of the test statistic and the ?-value. Do not use a
continuity correction for the ?-value. Give the sum of ranks to one
decimal place, the mean...
