In order to determine whether the median distance for the X-Special golf ball exceeds the median distance for the best-selling golf ball, six golfers were selected and asked to hit each ball with their driver. The distance was recorded.
 
  The following data were observed.
 
  Golfer X-Special Best Seller
  1 240 233
  2 267 270
  3 255 240
  4 234 230
  5 250 260
  6 285 270
 
  Based on these, the appropriate test is the Kruskal-Wallis one-way analysis of variance.
   Indicate whether the statement is true or false

Q. 2

The Wilcoxon Matched-Pairs Signed rank test is an alternative to the paired sample t-test when we are unwilling to assume that the populations are normally distributed.
 
  Indicate whether the statement is true or false

Q. 3

If a decision maker wishes to test to determine whether the medians are equal for two populations the Mann-Whitney U test is appropriate for either independent or dependent sampling situations.
 
  Indicate whether the statement is true or false

Q. 4

A large sample Mann-Whitney U test should be used when the sample sizes exceed 20.
 
  Indicate whether the statement is true or false

Q. 5

In conducting a Mann-Whitney U test when the sample size is greater than 20, the U test statistic can be assumed normally distributed.
 
  Indicate whether the statement is true or false

Q. 6

Recently, a study was done to determine whether the median speed on a section of highway is the same for cars versus trucks. A sample of 12 cars (n1 = 12 ) and 15 trucks (n2 = 15 ) was collected.
 
  If the Mann-Whitney U test is to be performed using an alpha = .05, the test critical U value is 49. Indicate whether the statement is true or false

Q. 7

A claim was recently made that stated that the median income for male and female graduates is the same for those graduating with a degree in operations management. The following sample data were collected:
 
  Males Females
  42,000 39,000
  36,000 39,000
  40,000 41,000
  32,000 42,000
  50,000 44,000
  47,000 38,000
  47,000 51,000
 
  In employing the Mann-Whitney U test, the sum of the ranks for the males is 53.5
   Indicate whether the statement is true or false
