Question: Task 1 (Scatterplot and correlation basics):
Using the data from the following table (which appears in our textbook):


  1. Draw a scatterplot by hand (using graph paper and proper scales)
    b.  Describe whether the data show any pattern and whether the two variables are correlated (positively or negatively)
    c.  Using the correlation simulation (http://bcs.whfreeman.com/scc/content/cat_040/spt/correlation/correlationregression.html)
    from the Moore textbook, reproduce the pattern from your hand drawn scatterplot and thus arrive at an estimate of the correlation coefficient; print the scatterplot from the simulation or take a screen shot and submit electronically.
    d. Do the same, but separately for two groups of countries (the five more developed countries [incl. Turkey] vs. the five less developed countries). Produce two scatterplots with regression line and correlation coefficient.
    e. In specting these three scatter plot and related correlation coefficients as well as using your general knowledge, what conclusions do you draw on whether there is a relationshiop between "mean caloric intake (all residents)" and "infant mortality rate".
