Suppose there is 1 dependent variable (dissolved oxygen, Y) and 3 independent variables (water temp X1, depth X2, and hardness of water X3). Below is the result of the multiple linear regression.Which of the three independent variable(s) is (are) significant predictor(s) of dissolved oxygen? water temperature only since its p-value is less than 0.05 level of significance intercept only since it has the greatest t statistic depth and hardness since their p-values are greater than 0.05 level of significance water temperature and intercept since their p-values are less than 0.05 level of significance
