24. (Correlation) A researcher wants to determine if there is a linear relationship between height and weight. The following table represents the data collected. Display the data in a scatter plot on your calculator, draw a quick sketch below. Then find the linear regression and put the line of best fit on the sketch. Then state the value for the correlation coefficient and determine if this is significant correlation or no correlation using the table in the back of the...
