Problem 9BSC
Appendix B Data Sets.Refer to the sample data for the given exercise. Use the Wilcoxon signed-ranks test for the claim about the median of a population.
Exercise
Refer to the indicated data set in Appendix B and use the sign test for the claim about the median of a population.
Testing for Median Weight of Quarters Refer to Data Set 21 in Appendix B for the weights (g) of randomly selected quarters that were minted after 1964. The quarters are supposed to have a median weight of 5.670 g. Use a 0.01 significance level to test the claim that the median is equal to 5.670 g. Do quarters appear to be minted according to specifications?

Solution 9BSC
The value of the test statistic T is equal to the smaller of the two sums.
So the value of the test statistic is 0 that is.
The sample size for the Wilcoxon signed rank test is equal to the number of pairs with
