QUESTION:
refer to the indicated data set in Appendix B and use the Wilcoxon rank-sum test. Weights of Coke ?Data Set 19 in Appendix B lists weights (lb) of the cola in cans of regular Coke and diet Coke. Use a 0.05 significance level to test the claim that the samples are from populations with the same median. If there appears to be a difference, try to explain it.
ANSWER:Solution 12BSC Step 1 : Given, A sample of 12 weights of cola in cans of regular coke and 12 weights of cola in cans of diet coke, 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. The data is given below .Hypothesis : H 0 The median of weights of the regular coke is same as the median of weights of the diet coke H : The median of weights of the regular coke is same as the median of weights of 1 the diet coke
