(a) Find the means (7 and g).
(b) Find the standard deviations (s, and s,).
(c) Find the correlation coefficient (r).
(d) Produce a scatter plot.
2. Based on the data set of Problem 1, find the best point-estimate of the volume of the foam,
when the temperature of the vinegar is 65°F. For an extra credit, back up your computation
visually, by presenting the scatter plot and the regression line.
3. Based on the data set of Problem 1, find the best point-estimate of the temperature of the
vinegar, if the volume of the foam is 380ml. For an extra credit, justify your computation
visually, by presenting the scatter plot and the regression line.
