Data is collected to assess the relationship. Which of the following would be true in the analysis? O The dependent variable is temperature and independent variable is yield. O On the associated fitted line (scatter) plot of the data, yield would be on the y axis and temperature on the x axis. O Assuming the engineer is correct, the correlation will be negative. O All of the above.Question 18 3 pts Which of the graphs has a higher correlation value? A B A because the data on graph A appear closer to the best fit line. O B because the data on graph B appear more dispersed from the best fit line. O They appear to have the same correlation Not able to determine from the plots
