Chapter 1.1, Problem 37E

To determine

To find : values of a, b, c and d

Answer to Problem 37E

  a=50,b=0,c=10,d=40

  a=20,b=30,c=40,d=10

Explanation of Solution

Given information : Row and column totals for a two-way table with two rows and two columns.

Calculation :

  

Take a=50,b=0,c=10,d=40

So,

  a+c=50+10=60

  b+d=0+40=40

  a+b=50+0=50

  c+d=10+40=50

Take a=20,b=30,c=40,d=10

So,

  a+c=20+40=60

  b+d=30+10=40

  a+b=20+30=50

  c+d=40+10=50
