The Department of Education would like to test the hypothesis that the median debt load of graduating students with a Bachelor's degree is equal to 17,000.
The following table summarizes the debt load of a random sample of graduating students with a Bachelor's degree.Debt Load Number of Graduating StudentsBelow 17,000 31Equal to 17,000 1Above 17,000 22The appropriate nonparametric procedure for this analysis is the _________________ test.A) sign
B) Wilcoxon signed-rank
C) Kruskal-Wallis
D) Wilcoxon rank-sum
Question 2
A retail chain would like to test if a difference exists between the variability of customer satisfaction scores from two locations.
The following data represents satisfaction scores from a random sample of customers from these locations on a scale of 1-20.Location 1 12 14 20 18 15 17 16Location 2 18 19 17 18 16 20 Using = 0.10, the conclusion for this hypothesis test would be that because the test statistic is ___________________ _________.A) more than the critical value, we fail to reject the null hypothesis and conclude that a difference exists between the variability of customer satisfaction scores from two locations
B) more than the critical value, we reject the null hypothesis and cannot conclude that a difference exists between the variability of customer satisfaction scores from two locations
C) less than the critical value, we can reject the null hypothesis and conclude that a difference exists between the variability of customer satisfaction scores from two locations
D) less than the critical value, we fail to reject the null hypothesis and cannot conclude that a difference exists between the variability of customer satisfaction scores from two locations
