The following method was proposed to estimate the number of people over the age of 50 who reside in a town of known population 100,000: "as you walk along the streets, keep a running count of the percentage of people you encounter who are over 50. do this for a few days; then multiply the per- centage you obtain by 100,000 to obtain the esti- mate." comment on this method. hint: let p denote the proportion of people in the town who are over 50. furthermore, let α1 denote the proportion of time that a person under the age of 50 spends in the streets, and let α2 be the cor- responding value for those over 50. what quantity does the method suggested estimate? when is the estimate approximately equal to p?
