The answer is 30, because you have to retrieve the totals. The total amount of people who have bikes is 72. The total amount of people with skateboards is 42. Subtract 42 from 72. You get 30.
Answer: 30.

Hope this helps! ^_^

30 more students have bikes than skateboards.

What is contingency table?

A table of data in which the row entries arrange the data concurring to one variable and the column entries organize it according to another variable and which is used particularly in the study of the correlation between variables.

Now the given contingency table is:

                                 Have Bikes             Do Not Have Bikes         Total

Have Skateboards                32                        10                               42

Do Not Have Skateboards    40                        12                               52

Total                                         72                       22                               94

Total number of students who have bikes=72

Total number of students who skateboards=42

Difference =72-42

                  =30
