Use the program MEDIAN to find an approximate 95% confidence

interval for the median income for the population sampled in

(Note: n =50.)

(a) Use the program TCONFINT to find a 95% confidence interval

for the true average height of the population sampled in

(Note: n = 50.)

(b) Use MEDIAN and the above sample data to find a 95% confidence

interval for this true average height. Compare with the

interval in part (a).
