Here are some random variables of different kinds. What sort of density shape do you think each would have? (Look in particular at the symmetry, kurtosis angles, and whether the shape might be bimodal, meaning it might have two peaks rather than one.)

(i) Daily stock market returns.

(ii) The weights (in pounds or kilos) of the population at large.

(iii) The weights of money market dealers.

(iv) Incomes in the population at large.

(v) The number of tourists eaten by crocodiles in Queensland each year.

(vi) The distribution of grades in your class on the next exam.
