For this question, the margin of error was given as 8%.
00:05
Let me take notes.
00:06
Margin of error denoted by m .e.
00:08
This is 8 % as a decimal number.
00:10
This is 0 .08.
00:12
And the confidence level, which is given as 99 % with decimal numbers.
00:17
This is 0 .99.
00:19
And the proportion not given here, we just assume the proportion as 0 .5.
00:23
So we have to get the sample size here, which is denoted by n.
00:27
In order to get the sample size, we have to use the margin of error for the proportion.
00:31
Let's remember this formula.
00:33
The margin of error for the proportion, which is z alpha over 2, square root of, this is p, 1 minus p, and divide by n...
