Assume that a Kruskal-Wallis test is being conducted to determine whether or not the medians of three populations are equal. The sum of rankings and the sample size for each group are below.
 
  Group 1 Group 2 Group 3
  R1 = 60 R2 = 36 R3 = 24
  n1 = 6 n2 = 5 n3 = 4
 
  The value of the test statistic is H = 0.68
   Indicate whether the statement is true or false

Question 2

A recent study was conducted to determine if any of three suppliers of electronic components has a different median delivery time on special orders. To test this, five orders were given to each supplier and the delivery days were recorded.
 
  These data are shown as follows:
 
  Supplier 1 Supplier 2 Supplier 3
  15 11 15
  19 7 9
  13 19 5
  10 10 12
  20 12 10
 
  If a Kruskal-Wallis test is to be performed, the critical value for a test conducted using an alpha = .05 level is 2 = 11.0705
   Indicate whether the statement is true or false
