Topic: Signed rank test 11811 Chapter 01  An Introduction to Business Statistics 33. Two NFL scouts are in the process of recruiting 7 college senior football players
(receivers). After a careful review and evaluation, both scouts ranked the seven receivers in
terms of their professional career prospects. If we want to determine whether the two scouts
have similar opinions about the professional football career prospects of the seven players,
which one of the following nonparametric tests would be chosen?
A. Wilcoxon signed rank test
B. Wilcoxon rank sum test
C. Sign test
D. KruskalWallis test

Topic: Rank correlation coefficient 34. In a manufacturing facility producing fasteners, a foreman suspects that the diameter of
the bolt produced by his second shift workers is greater than the diameter of the bolts
produced by his first shift workers. He takes a sample of 5 bolts from the first shift and a
sample of 4 bolts from the second shift and measures the diameters in inches. Distribution of
bolt diameter measurements is not normally distributed. Which one of the following
nonparametric tests is appropriate for this problem?
A. Wilcoxon signed rank test
B. Wilcoxon rank sum test
C. Sign test
D. KruskalWallis test

of one population has shifted to the right or to the left of the probability distribution of another
population.

Topic: Sign Test 11815 Chapter 01  An Introduction to Business Statistics 40. Refer to the MegaStat/Excel output for the Wilcoxon rank sum test given in the table
below. At a significance level of .05, which one of the following statements is correct regarding the
following null hypothesis?
H0: D1 is shifted to the right or left of D2
A. We reject H0 and conclude there is very strong evidence that the median value of the first
sample significantly differs from the median value of the second sample.
B. We reject H0 and conclude there is very strong evidence that the median value of the first
sample is significantly less than the median value of the second sample.
C. We failed to reject H0 and conclude there is not sufficient evidence that the median value
of the first sample is significantly less than the median value of the second sample.
D. We failed to reject H0 and conclude there is not sufficient evidence to conclude that the
median value of the first sample is not significantly different than the median value of the
second sample.
E. We failed to reject H0 and conclude there is very strong evidence that the median value of
the first sample is significantly greater than the median value of the second sample. AACSB: Reflective Thinking
