Answer 1

Families were surveyed to see how they spent summer vacation.
The results are as follows:
                                     Camping  Traveling out of state   Activities in local area
1 or more children < 16       30                16                           44
All children 16 or older        22                60                            28

I'll just make my own two-way relative frequency table. A two-way relative frequency table is called such because each value is computed based on the total of the number of the whole table.
I'll just use codes to make the table fit in this screen.

                A        B       C          TOTAL
1             30      16      44            90
2             22      60      28           110   
TOTAL    52      76      72           200

Two-way relative frequency table:
  
                A                              B                          C                TOTAL
1             30/200=0.15      16/200=0.08      44/200=0.22    90/200=0.45
2             22/200=0.11      60/200=0.30      28/200=0.14   110/200=0.55   
TOTAL    52/200=0.26      76/200=0.38     72/200=0.36    200/200=1.00

Among the given choices, my answer would be the 1st choice.

Summer vacation Camping Traveling out of state Activities in local area Row totals At least one child under 16 0.15 0.08 0.22 0.45 All children 16 or older 0.11 0.30 0.14 0.55 Column totals 0.26 0.38 0.36 1
