Solution 8BSC Step 1 : Given, The amount of In the above example the data consists of the the amount of strontium-90 in a simple random sample of baby teeth obtained from Pennsylvania residents and New York born after 197921 , so the observations from the same population. Hence first requirement of the Wilcoxon Rank-Sum test satisfied. Each samples contains 12 values, it satisfies the second condition that the each sample should have the same median. Therefore, both the requirements of the Wilcoxon Sum-Rank test satisfies. Hypothesis : H 0 The median amount of strontium-90 from Pennsylvania residents is equal to the median of The median amount of strontium-90 from New York residents. H 1 The median amount of strontium-90 from Pennsylvania residents is not equal to the median of The median amount of strontium-90 from New York residents.
