Wastewater and industrial pollutants discharged into water sources can lower the dissolved oxygen content of the water and adversely affect aquatic species. In one study, measurements were made at one-week intervals from the same point of a river for 2 months.

week	dissolved O₂ ppm

2	5,1
3	5,6
4	4,3
5	4,7
6	4,9
7	4,5

Some scientists consider a concentration of 5.0 ppm for dissolved O₂ to be the lower limit of the level required for fish to survive. Test if the average dissolved O₂ concentration is less than 5.0 ppm by performing a statistical test. State clearly the null hypothesis and the alternative hypothesis.
