In a study of the nitrate contamination of groundwater in the Nakdong River Basin (Korea), it was found that 22 out of 41 water samples taken from wells in the Daesan area met quality standards for drinking water. Over the entire Nakdong River Basin, it is known that 58% of wells meet water quality standards. Does the sample result indicate that the proportion of wells in the Daesan area that meet water quality standards is significantly different than the proportion for the rest of the Nakdong River Basin? State the null and alternative hypotheses, and give the formula for the test statistic that you would use but do not perform any calculations.
