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. make an inference about which fish increased its predicted average population from year 1 to year 2. all three types of fish increased their predicted average population. trout increased its predicted average population. bass increased its predicted average population. none of the fish increased their predicted average population.\nyear 1 sample 1 sample 2\ntrout 3 5\ncatfish 9 9\nbass 8 6\nall fish 20 20\nyear 2 sample 1 sample 2\ntrout 8 10\ncatfish 10 9\nbass 2 1\nall fish 20 20
Answer
Explanation:
Step1: Analyze Trout population
In Year 1, Trout sample 1 has 3 and sample 2 has 5. In Year 2, sample 1 has 8 and sample 2 has 10. The population has increased.
Step2: Analyze Catfish population
In Year 1, Catfish sample 1 and 2 both have 9. In Year 2, sample 1 has 10 and sample 2 has 9, no clear - cut overall increase.
Step3: Analyze Bass population
In Year 1, Bass sample 1 has 8 and sample 2 has 6. In Year 2, sample 1 has 2 and sample 2 has 1, the population has decreased.
Answer:
Trout increased its predicted average population.
