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 Step 1 The given problem explain about testing for Median Weight of Quarters. From the given problem we use the Wilcoxon signed-ranks test for the claim about the median of a population. We know that the given data are a simple random sample. Here we have to check the symmetry. Then we have to find the differences and it is denoted by d. Now,we are subtracting taxi-out time (min) and taxi-in times(min). The table as shown in below.
