Question:

In a study on small-group dynamics, sociologists found that when 10 members of a discussion group were ranked according to the number of times each participated, the number N(k) of times that the kth-ranked person participated was given by

N(k) = N1e-0.11(k - 1) 1 ≤ k ≤ 10

where N1 is the number of times that the first-ranked person participated in the discussion. If N1 = 180, in a discussion group of 10 people, estimate how many times the sixth-ranked person participated. How about the 10th-ranked person?
