In statistics confidence intervals are constructed to estimate the population parameter.
00:12
So, in this case the population mean with a certain level of confidence.
00:16
Now the level of confidence reflects the level reflects the probability of the interval that the interval will be will contain the true population parameter.
00:33
Now let us discuss the three that are given.
00:35
So, the 90 percent confidence interval it will be relatively narrower.
00:40
So, you are 90 percent sure.
00:42
So, it will be narrower compared to the others because it is constructed to obtain the population mean with 90 percent confidence.
00:57
So, this means that if you were to repeat the process of constructing the 90 percent confidence interval many many times.
01:07
So, you would expect 90 percent of those intervals to contain the true population mean...
