Also, the water hardness was recorded as the calcium concentration (parts per million or ppm) in the drinking wawr. The scatterplot and the regression analysis ofthe relationship between mortality and calcium concentration, where the dependent variable is Mortality, are shown below. Complete parts a through d.
