The data in the table below are 55 smiling times, in seconds, of an eight- week-old baby. We will assume that the smiling times, in seconds, follow a uniform distribution between zero and 23 seconds, inclusive. This means that any smiling time from zero to and including 23 seconds is equally likely. What is the probability that a randomly chosen eight-week-old baby smiles between two and 18 seconds? *
