Complete the following in regard to the footlength and height categories of the data set:

In the region to the right, produce a scatterplot of the footlength versus height data (remember this means height runs along the horizontal axis as the independent variable and footlength along the vertical axis as the dependent variable.) Based upon your scatterplot, briefly discuss below your thoughts on whether the “visual” trend between the individuals’ footlength and height appears linear, curvilinear, or has no general trend at all.

Complete the following:

Include the trend line's graph and equation 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.

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

Determine the value of the correlation coefficient for this paired data. Explain what this value tells you and determine if it implies that there is/is not statistically significant correlation between the two variables of height and footlength. (Recall the need to use table A:6 from the text in answering the last portion of this question.)

Using the predicition equation from part bi. above, predict the footlength of an individual whose height is 160 cm.

Finally, critique the statement “since the correlation coefficient is statistically significant” then this means that “being tall causes one to have a long foot.” Specifically, address the issue of “causation” in relation to significant statistical correlation.
