For two years, two samples of fish were taken from a pond. Each year, the second sample was taken six months after the first sample.

2 tables. A 3-column table with 4 rows. Column 1 is labeled Year 1 with entries trout, catfish, bass, all fish. Column 2 is labeled Sample 1 with entries 3, 9, 8, 20. Column 3 is labeled Sample 2 with entries 5, 9, 6, 20. The second table is a 3-column table with 4 rows. Column 1 is labeled Year 1 with entries trout, catfish, bass, all fish. Column 2 is labeled Sample 1 with entries 8, 10, 2, 20. Column 3 is labeled Sample 2 with entries 10, 9, 1, 20.

Make an inference about which fish increased its predicted average population from Year 1 to Year 2.
