a. Construct a frequency distribution

b. Construct a bar graph

c. Construct a pareto chart

d. Construct a pie graph

e. In which rating category are most people visiting a local library.

Answer 1

a. Construct a frequency distribution

Objective	Frequency
S	8
MS	5
C	7
Total	20

b. Construct a bar graph

c. Construct a pareto chart

Now, the following table shows the categories in descending order (with respect to the frequencies), along with the cumulative relative frequencies

Categories	Frequencies	Cum. Relative Frequencies (%)
S	8	40
C	7	75
MS	5	100
Total =	20

Therefore, the following Pareto Chart is obtained based on the table above:

d. Construct a pie graph

Category	Freqency	Proportion	Percentage
S	8	0.4	40
MS	5	0.25	25
C	7	0.35	35

e. In which rating category are most people visiting a local library.

As S is 40%
