Inferential statistics, which are based on laws of probability, allow researchers to make inferences about a population based on data from a sample; they offer a framework for deciding whether the sampling error that results from sampling fluctuations is too high to provide reliable population estimates. - answer- The sampling distribution of the mean is a theoretical distribution of the means of an infinite number of samples drawn from a population. The sampling distribution of means follows...

The Sustainable Development Goal (SDG) 6.1 aims to ensure that “safely managed drinking water services” are free of fecal pollution.1 Evaluating the presence of fecal pollution is difficult in low-resource settings partially due to lack of financial, logistical, and technical resources. In such settings, organoleptic properties (smell, taste, and appearance) are relied upon to infer the quality of drinking water. There are no published studies that have evaluated the associations of...
