Also, the water hardness was recorded as the calcium concentration (parts per million or ppm) in the drinking water. The scatterplot and the regression analysis of the relationship between mortality and calcium concentration, where the dependent variable is Mortality, are shown below. Complete parts a through d. K Click the icon to view the scatterplot and regression analysis. a) Is there an association between the hardness of the water and the mortality rate? Write the appropriate hypotheses. t A. H0:1=0vs. HA: 10 D. H0:|310 vs. HA: [31 =0 b) Assuming the assumptions for regression inference are met, what do you conclude at the 0.05 level of signicance?
