Answer:

Yes, there is a relationship between.

Explanation:

From the table, for people younger than 18 years, 317 use outdoor pool while 41 use indoor pool.

Thus;

% younger than 18 that use indoor pools = (41/(317 + 41)) × 100% = 11.45%

% younger than 18 that use indoor pools = (317/(317 + 41)) × 100% = 88.45%

So we can see that there is a relationship whereby the percentage of younger than 18 that use indoor pools is less than that of those that use outdoor poles.

In the same vein, by inspection, percentage of 18 or older that use outdoor poles are more than the percentage of % younger than 18 that use indoor pools.

Thus, there is a relationship between pool type and age group.
