test to determine a conclusion using the 10% at 5 ppb condition. Analyze the Virginia Tech Study Is there convincing statistical evidence that the Flint water system is unsafe. A Virginia Tech study {2015) randomly sampled water from 252 homes in Flint. Of those, 42 had high lead content that exceeded 15 ppb and 101 samples were over 5 ppb. 1.] Test the hypothesis that more than 10% of homes in Flint have lead level that r! 20.05 exceeds 5 ppb, use . State the null and alternative hypothesis, state the p-value, make the decision to reject or fail to reject the null and based on that write the appropriate conclusion. 2.) Test the hypothesis that more than 10% of homes in Flint have lead level that r! 20.05 exceeds 5 ppb, at using either the MDEQ 69 sample data or the 71 samples. State the null and alternative hypothesis, state the p-value, make the Project Part 3 In August 2015, Marc Edwards, a professor at Virginia Tech University, creator of FlintWaterStudy.org, and an expert in water quality measures, had his research team send out 300 water testing kits to Flint residents, 252 were returned and analyzed. Virginia Tech released their results on September 8, 2015, showing a conflict with the MDEQ study. From the 252 samples returned, 101 were over 5 ppb and 42 of those samples exceeded the 15 ppb action level. Additionally, the highest lead amount in first draw (just turning on the faucet) was 158 ppb and the highest sample after 45-seconds of flushing was over 1000 ppb. When running the test, residents often had to turn their water on for a while to flush out any water that was in the home itself. The running of water for 45-seconds to flush the lines would provide good evidence of external contamination. The water already inside the house would be pushed out and down the drain, leaving water coming in from the water main to replace what was in the house. Because the samples were not of worst-case homes in Flint, the Virginia Tech team came up with a baseline threshold of 10% with a lead level of 5 ppb. They believed that if more than 10% of these representative (not worst-case) homes were over 5 ppb, that the lead problem was widespread and not just involving a small set of homes. Perform the appropriate hypothesis test to determine a conclusion using the 10% at 5 ppb condition.decision to reject or fail to reject the null and based on that write the appropriate conclusion. 3.) According to EPA, if more than 10% of homes in a city have high lead content in their water, above 15 ppb, the city's water supply is unsafe. Use the Virginia Tech data to test the claim that more than 10% of homes exceed 15 ppb, at rx.' :0.05 . State the null and alternative hypothesis, state the p-value, make the decision to reject or fail to reject the null and based on that write the appropriate conclusion
