A researcher has conducted a study on the importance of environmental sustainability in preserving recources like clean air, water, wildlife for future generations. The following table represents the responses of 50 randomly selected respondents in this survey.

very important	important	fairly important	very important	fairly important	important
important	slightly important	not important	fairly important	important	very important
fairly important	fairly important	important	very important	very important	important
important	very important	important	slightly important	fairly important	fairly important

1. Construct a frequency table to represent the data above.
2. Calculate the relative frequency for each type of response.
3. Develop a bar chart for the distribution.
4. Based on your bar chart in c), describe the distribution of this survey.
5. This study use the 5-point Likert Scale as below:

not important	slightly important	fairly important	important	very important
1	2	3	4	5

Calculate the following:

1. mean
2. mode
3. median
4. variance
5. standard deviation
6. Pearson's coefficient of skewness
