We wish to be able to see if we can reasonably predict an adult's height by knowing armspan measurement.Complete the following in regard to the Height and Armspan factors in the data set:

a. Include the trend line's graph and equation (least squares line) on the scatterplot created in part a.Give the line's equation below and explain within this context what the "x" and "y" variables represent in the equation.

b. Below, explicitly state the slope of your trend line and discuss what the value of the slope signifies in terms of this context.

c. Determine the value of the correlation coefficient (r) for this paired data.Explain what this value tells you regarding these two variables.Next, determine the value of the coefficient of determination (r^2) for this paired data.Explain what this value tells you regarding these two variables.

d. Using the least squares linear prediction equation from part bi. above, predict the height of an individual whose armspan is 162 cm.

e. Finally, critique the statement "since the correlation coefficient is strong positive correlation" then this means that "having a longer armspan causes causes one to be taller."Specifically address the issue of "causation" in relation to statistical correlation.
