Answer (C) is correct . A simple regression can be calculated using the formula for a straight line: y = a + bx ? Where:? y = the dependent variable a = the Y-axis intercept b = the slope of the regression line x = the independent variable Solving with the information given yields the following results: y = a + bx = 5.23 + (1.54 ¡Á 10) = 5.23 + 15.4 = 20.63Answer (A) is incorrect because The figure 6.77 results from simply adding the intercept and slope.
Answer (B) is incorrect because The figure 8.05 results from simply multiplying the intercept and slope.
Answer (D) is incorrect because The figure 53.84 results from transposing the intercept and slope.
