Question

select the true statements about the data. the five - year period with the highest average kelp canopy area was from 2004 to 2008. the five - year period with the lowest average kelp canopy area was from 2015 to 2019. the average kelp canopy area fluctuates from year to year. the average kelp canopy area has steadily increased since 1985.

Explanation:

1. If data shows 2004 - 2008 has highest average kelp canopy area among five - year periods, first statement is true.
2. If 2015 - 2019 has the lowest average among such periods, second statement is true.
3. Year - to - year changes in average area imply fluctuations, so third statement is likely true if data supports.
4. Since there are periods of high and low areas, average has not steadily increased since 1985, so fourth statement is false.

The five - year period with the highest average kelp canopy area was from 2004 to 2008.
The five - year period with the lowest average kelp canopy area was from 2015 to 2019.
The average kelp canopy area fluctuates from year to year.
