An industrial plant dumps its waste into a nearby river and you want to investigate the level of calcium concentration downstream to determine if it might be negatively impacting the native fish. So you measure the calcium concentration from a random sample of 15 locations in the river and calculate a mean of 96.9 mg/L, with a standard deviation of 3.1 mg/L. Estimate the mean calcium concentration in the river with 95% confidence. Given: critical value = 2.15
