The following is the distribution of ages of students in a graduate course:

(a) Construct a bar chart of the data.

(b) Calculate the mean and standard deviation of the data.

Make scatterplots for all pairwise combinations of the variables from the tree data (Table 1.7). Which pairs of variables have the strongest relationship? Is your conclusion consistent with prior knowledge?
