Answer to Problem 8.48E
Not binomial.
Explanation of Solution
The four conditions for a binomial setting are: binary (success/failure), independent trials, fixed number of trials and the probability of success is the same for each trial.
Binary: long/short last name.
Independent: Yes, the length of someone’s name is not dependent on the length of the name of someone else.
Number:
Success: No, the probability of success does not remain the same on each draw as the names are drawn without replacement.
Thus the setting is not binomial.
