# Question: For a contingency table with r rows and k columns

For a contingency table with r rows and k columns, determine the df for the test if

a. r = 3, k = 4

b. r = 2, k = 3

c. r = 4, k = 5

d. r = 5, k = 3

e. r = 3, k = 7

f. r = 3, k = 3

a. r = 3, k = 4

b. r = 2, k = 3

c. r = 4, k = 5

d. r = 5, k = 3

e. r = 3, k = 7

f. r = 3, k = 3
