The Queen decided to change the distribution of wealth in Arecima. With the help of the royal statistician, Excelier, Cecillia redistributed wealth so that the new distribution remains Normal but the mean was increased from 100 (thousand dollars) to 120 (thousand dollars) and the standard deviation was reduced from 20 to 10 (thousand dollars). This was accomplished by transferring 5% of her own wealth to her people as well as changing the wealth of some of the Arecimians such that each person's ranking (i.e., from the poorest to the richest) remained the same. More precisely, if any given person's wealth was initally at the k- th quantile of the wealth distribution, her/his wealth remains at the k-th quantile of the new distribution. 27.
