Give an example of a set of data for which the mode best represents the data. Explain.

Suppose that the Sun runs out of nuclear fuel and suddenly collapses to form a so-called white dwarf star, with a diameter equal to that of the Earth. Assuming no mass loss, what would then be the new rotation period of the Sun, which cur- rently is about $25$ days? Assume that the Sun and the white dwarf are uniform spheres.
