Correlation: r = .70 Regression Equation:90X.30 Explain what a tells you in the regression equation above. If someone has no children living with them, you would expect them to miss .30 (or no) classes. O If someone has no children living with them, you would expect them to miss.90 (or 1) class. O If someone is taking no classes, you would expect them to have .30 (or no) children living with them. O If someone is
