Please help with the 5 parts of this question. (the selected answers were marked as incorrect.
After a heavy storm, the waste water holding tanks at a waste water treatment plant on the New River overflowed dumping 1,000,000 gallons of sewage into the New River. You are part of the New River Citizen Watch Group, which monitors the health of portions of the New River for government agencies like the EPA and USDA. This sewage discharge event causes your group to wonder if the event has had a negative impact on the quality of the water downstream of the waste water treatment plant. To test your group's idea that the sewage has negatively impacted water quality, you measure in triplicate the % EPT of a site upstream of the waste water treatment plant and a site downstream of the waste water treatment plant. You calculate the mean % EPT of both sites and the 95% confidence intervals of both samples. Your results are shown below. Use this scenario and data to answer the following questions. 120 100 80 60 40 20 0 Upstream site Downstream siteExplanation / Answer
1. b- The downstream result has more variation due to longer deviation line on the bar graph.
2 d- there is not enough data to answer this.
3 b The result is inconsistent with the prediction.
4 d The hypothesis is neither accepted nor rejected.
5 d- theere is no enough data to answer this.
