The water quality in the Athabasca River located in Alberta, is frequently measured as it is adjacent to several open pit mines and crude oil extraction sites. Copper is considered a priority pollutant as it can severely impact the health of the aquatic ecosystem if it is in concentrations above 601. Suppose over one year 34 water quality samples are taken from the river and the mean concentration of copper was calculated to be 61.81. Given that for the samples taken =61, does this data provide evidence that the concentration of copper in the Athabasca River is above the tolerable concentration?
