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?

Step-by-Step Solution:

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. Step 2 Now the histogram of the differences is in below. From the above histogram the mirror image of the right side is nearly to the left side of the histogram.So the differences are symmetric and the second condition of the Wilcoxon signed rank test is satisfied as well.
