The proportion value given here, which is 0 .25, and the sample size, which is given as 150.
00:08
So what we need, we need the mean value.
00:10
So the mean for the proportion, which is equal to the p -value here, so the p -value is 0 .25, and the standard deviation for the proportion, which is the square root of, this is, sorry, this is p times 1 minus p, and divide by n.
00:28
Let's get the standard deviation from here.
00:30
So what we're going to do, we're going to do standard deviation, which is equal to square root of, this is 0 .25 times 1 minus 0 .25, and this is divided by the sample size, which is 150.
00:47
Let's get this result.
00:48
This is the square root of 0 .25 times 1 minus 0 .25, which is and this is divided by 150.
00:57
So the value would be, which is 0 .03 and 54 with four decimal places...
