Complete the following problem to understand the various steps that may be incorporated into the scientific process. there is no dispute that the levels of nitrogen-containing compounds have increased in the world's water supply due to increased use of fertilizers and combustion of fossil fuels. according to the world health organization, many communities are exposed to drinking water that exceeds the present standard for nitrate (no3) in drinking water. as such, there is a growing concern for how increased levels of nitrates in drinking water can affect human health. imagine that you are interested in the role that this problem plays in your own community. upon investigation, you learn that scientists have developed the hypothesis that increased nitrates in drinking water are associated with increased cases of methemoglobinemia in infants, a disease that interferes with the oxygen-carrying capacity of blood. further, you learn that there is typically a higher concentration of nitrates in water drawn from private wells compared to water drawn from public wells given this information, which of the following is an appropriate projection that would test the hypothesis that there is a link between nitrates in drinking water and methemoglobinemia? o public wells are the cause of infant diseases like methemoglobinemia. o methemoglobinemia will be less prevalent among infants who live in areas that have private wells instead of public wells. o the number of cases of methemoglobinemia will be higher among infants who drink from private wells compared to infants who drink from public wells
