(d) Predict the value of y for x = 1.5. Choose the correct answer below. O A. 46.4 O B. 48.8 O C. 98.7 O D. not meaningfulFind the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation.) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful.
