Complete the following in regard to the footlength and height categories of the data set:
Below, explicitly state the slope of your trend line and discuss what the value of the slope signifies in terms of this context. Using the predicition equation from part bi. above, predict the height of an individual whose footlength is 22.45 cm.Using the predicition equation from part bi. above, predict the height of an individual whose footlength is 22.45 cm.Using the predicition equation from part bi. above, predict the height of an individual whose footlength is 22.45 cm.Using the predicition equation from part bi. above, predict the height of an individual whose footlength is 22.45 cm.Using the predicition equation from part bi. above, predict the height of an individual whose footlength is 22.45 cm.
a. In the region to the right, produce a scatterplot of the height versus footlength data (remember this means footlength runs along the horizontal axis as the independent variable and height 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.
b. Complete the following:

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