Peter analyzed a set of data with explanatory and response variables x and y. He concluded the mean and standard deviation for x as 7.8 and 3.70, respectively. He also concluded the mean and standard deviation for y as 12.2 and 4.15, respectively. The correlation was found to be 0.964. Select the correct slope and y-intercept for the least-squares line. Answer choices are rounded to the hundredths place. Slope = -1.08 O y-intercept 3.78 = Slope = 1.08 O y-intercept -3.78 Slope = 1.08 y-intercept 3.78 Slope = -1.08 y-intercept -3.78
