CR5.11 ● The paper referenced in Exercise CR5.10 also gave data on sodium content (in milligrams per kilogram) of 10 chocolate puddings made from instant mix:

3099 3112 2401 2824 2682 2510 2297 3959 3068 3700

a. Compute the mean, the standard deviation, and the interquartile range for sodium content of these chocolate puddings.

b. Based on the interquartile range, is there more or less variability in sodium content for the chocolate pudding data than for the tomato catsup data of Exercise CR5.10?
