How many exercises are there in Chapter 14?

Ans: there are total of 4 exercises in chapter 14 that is 14.1, 14.2, 14.3, 14.4

What is parameter term in statistics?

Ans: Any value or group of data we pass in order to get result of certain value is called parameter

What passing parameter is very important in statistics

Ans: We know very well that we will be getting accurate data when we pass the value by which we needed hence in order to work on accuracy we will be passing parameter in statistics
