In a learning experiment, cats were given successive trials at learning a complicated maze. A given cat was trained until he could traverse the maze without error five times in a row. If the cat could not go through the maze five times successfully after 30 trials, training was stopped. The numbers of trials it took each of 36 cats to learn this maze to the criterion is given below.

Construct a frequency distribution for these data.
