Question 1

The Mann-Whitney U test is a nonparametric test that is used to test whether two related populations have the same median.

Accepted Answer

A) True 
 B)False

Question 2

Recently,Major League Baseball officials stated that the median cost for a family of four to attend a baseball game including,parking,tickets,food,and drinks did not exceed $125.00.The following sample data were collected:   Assuming that the test of the owners' claim is going to be conducted using an alpha = .05 level,the null hypothesis that the median cost does not exceed $125 should not be rejected.

Accepted Answer

A) True 
 B)False

Question 3

Consider the situation in which a study was recently conducted to determine whether the median price of houses is the same in Seattle and Phoenix.The following data were collected.   Given these data,if a Mann-Whitney U test is to be used,the sum of the ranks for Seattle is:

D) 40. 
A) 43. 
B) 35. 
C) 25.5. 
D) 40.

Question 4

The Kruskal-Wallis test is used to test whether the centers of 3 or more populations are equal so long as that is the only possible difference between the population distributions.
