Frequency, Frequency Tables, and Levels of Measurement · Example 4

(a) Is the table correct? If it is not correct, what is wrong?
(b) True or False: Three percent of the people surveyed commute three miles or less. If the statement is not correct, what should it be? If the table is incorrect, make the corrections.
(c) What fraction of the people surveyed commute five or seven miles?
(d) What fraction of the people surveyed commute 12 miles or more? Less than 12 miles? Between five and 13 miles (not including five and 13 miles)? The cumulative relative frequency column should read: $\frac{2}{19}, \frac{3}{19}, \frac{4}{19}, \frac{7}{19}, \frac{9}{19}, \frac{12}{19}, \frac{14}{19}, \frac{15}{19}, \frac{16}{19}, \frac{18}{19}, \frac{19}{19}$
