Question 16 O Mark this question For a set of data, x is the explanatory variable, its mean is 8.2, and its standard deviation is 1.92. For the same set of data, y is the response variable. Its mean is 13.8, and its standard deviation is 3.03 The correlation was found to be 0.223. Select the correct slope and y-intercept for the least-squares line. O Slope = -0.35 y-intercept = 10.9 O Slope = -0.35 y-intercept = -10.9 O Slope = 0.35 y-intercept = 10.9 Slope = 0.35 O y-intercept = -10.9
