Exercise U5.2 Leonardo DaVinci drew a sketch of a man, indicating that person's arm span (measuring across the back with arms outstretched to make a >) is roughly equal to the person's height. To test this claim, we measured eight people with the following results: Person 2 3 4 5 6 7 8 Arms span (cm) 172.7 158.1 165.1 176.5 172.7 175.3 157.5 153.0 Height (cm) 175.3 157.5 165.1 177.8 170.2 170.2 160.0 157.5 (a) Draw a scatterplot for arm span and height. Use the same scale on both the horizontal and vertical axes. Describe the relationship between two variables. (b) Calculate the correlation coefficient relating arm span and height. (c) If you were to calculate the regression line for predicting height based on a person's arm span, how would you estimate the slope of this line? (d) Find the regression line relating arm span to a person's height. (e) If a person has an arm span of 157.5 cm, what would you predict the person's height to be
