Explanation / Answer

R-Script

First row represents specifications i.e. discrete values

Second row represents frequencies of the corresponding discrete values

---------------------

If you were a teacher and had 30 students in your class and wanted to know the class average on the first quiz,

I have to use parameter since population size = N = 30, I collected all 30 students marks and calculate average of them. It is class mean or population mean. It is nothing but Parameter

-------------------

If you wanted to know how many people in your country recognize the name of your new company

In this situations, we have to use statistic since i draw some people in the country and ask them - are you know my company name? - Yes or no.

We get the information from sample So it is a statistic.
