Question 1:Regression EquationQuestion 1:Regression Equation
• Bottom table, Column = Coefficients• Row = intercept =a• Row = cholesterol = b = slope• Interpret slope: If X increases by 1 unit, Y
changes (increase? decrease?) by b units
• Bottom table, Column = Coefficients• Row = intercept =a• Row = cholesterol = b = slope• Interpret slope: If X increases by 1 unit, Y
changes (increase? decrease?) by b units
