1 point Below you have two datasets, each of them with two explanatory variables X2,X3 (plus the intercept). Which dataset present(s) a problem of exact collinearity? Dataset 1 only Dataset 2 only Both datasets None of them Cannot be answered with the information provided 1 point Below you have a dataset with two explanatory variables X2 and X3, and one dependent variable Y. Estimate the (partial) slope coefficient for X3. 0.6840.6470.3540.9860.245 1 point Below you have the estimates of a multiple linear regression that satisfies the CLRM assumptions. The independent variable How do you interpret the coefficient on X5? For each unit that X5 increases, Y decreases 0.084 units. For each unit that X5 increases, Y decreases 0.084 units on average. For each unit that X5 increases, Y decreases 0.084 units on average, holding the value of X2 constant. For each unit that X5 increases, Y decreases 0.084 units on average, holding the value of X3 constant. For each unit that X5 increases, Y decreases 0.084 units on average, holding the value of X4 constant. For each unit that X5 increases, Y decreases 0.084 units on average, holding the values of X2,X3 and X4 constant. 1 point Below you have two datasets, each of them with two explanatory variables X2,X3 (plus the intercept).
