Answer 1

Answer:

Relative frequencies

First row

0.8125 ,0.1875 ,16

Second row

0.555 ,0.444 ,9

third row

18 , 7 ,  25

Step-by-step explanation:

Given data

               allowance        No allowance          total

Chores         13                   3                          16

No chores      5                   4                           9

Total              18                   7                            25

Relative frequencies

               allowance          No allowance                  total

Chores         $\frac{13}{16} = 0.8125$     $\frac{3}{16} = 0.1875$                       16

No chores      $\frac{5}{9} = 0.555$      $\frac{4}{9} = 0.444$                            9

Total              18                   7                                   25
