Concentrations of a pollutant were measured at 25 locations in a lake after rains caused heavy runoff from surrounding areas. After a period of dry weather, they were measured again at the same locations. The data is attached in the image below. (a) Perform an appropriate hypothesis testing to see if there is any effect of the runoff on pollutant concentrations. (b) Find a 90% confidence interval for the effect of runoff on pollutant concentrations.
