So our question says, which of the following measures? how close the observed sample statistic has come to the hypothesized population parameter? we have the following options.
00:10
We have option a to be the test statistics.
00:12
We have option b to be the confidence, coefficients.
00:15
We have option c to be the sample size and we have option d to be the level of significance.
00:21
So before we'll answer this question, let's just quickly know the definitions of each and every one of this.
00:26
So let's start with option d, which is the level of significance.
00:28
So the level of significance is simply the probability of committing a type 1 error and we denote it as alpha.
00:36
So alpha is probability of committing a type 1 error.
00:48
So obviously this is not the answer.
00:50
The next one says the sample size...
