Hello friends, we are going to write here 61 % use social media, x value is given, n value is given.
00:08
We need to find 93 % confidence interval.
00:11
So, confidence interval is if i write here, what would be population proportion? this is p cap is x by n, which is 0 .71.
00:23
So, basically, this is p cap plus minus margin of error.
00:29
So, basically, if i write here for this, p cap value is 0 .71 plus minus z alpha by 2 multiplied by under root of if i write here for this 0 .71 multiplied by 1 minus 0 .71.
00:48
If i write here for this, this must be written as 1 minus 0 .71 that is 0 .29 and this must be divided by n, which is 2329.
01:04
So, basically, if i write here for this, this must be this must be written as 0 .71 if i write here plus minus z alpha by 2 at 93 % confidence interval is 1 .82 multiplied by under root of if i write here for this.
01:32
So, basically, if i write here, this total value must be calculated as we need to write here 0 .0171 which is 0 .71 plus minus if i write here, actually, this value will be calculated as 0 .0094 and this is 0 .0171...
