For solution of our first question here when a large number of individual are taken, individuals are taken who are different and similar in many ways then this is called a population.
00:42
And similarly for the parameter we have a small group of selected individual from the population who can represent or who can represent a larger group within the population that is known as a sample.
01:41
So, here we have described what is the population and what is the sample.
01:47
This is our solution of first part of the question.
01:52
So, here we have answer for first part.
01:55
Now, let's move on to the second part of the question.
01:58
For second part, we have to explain here central limit theorem.
02:08
So, in the simple words, we can see a large sample size, sample size will follow a normal distribution that is according to the central limit theorem and next we have normal distribution distribution so this distribution fits well and can be transformed transformed in a bell -shed well shaped and symmetric plot...
