Sometimes	552
Most of the time	1257
Always	2518

a. Construct a relative frequency distribution.
b. What percentage of respondents answered “Always”?
c. What percentage of respondents answered “Never” or “Rarely”?
d. Construct a frequency bar graph.
e. Construct a relative frequency bar graph.
f. Construct a pie chart.
