So just so you know, this did come over very blurry.
00:06
And i believe that this says 0 .3, and then it's a random sample size of 200.
00:11
And a sample population is used to estimate the population proportion.
00:19
Round your answer to four decimal places.
00:22
So four decimal places.
00:24
What is the probability that the sample proportion will be? i don't know what this says.
00:30
Within plus or minus 0 .04.
00:36
So what you're going to do is you're going to take the, so it's within, so if you do less than or equal to, so 0 .04, 0 .04, then then what you're going to do is you're going to take the square root of 0 .3 times 1 minus 0 .3 divided by 200.
01:21
And that equals 0 .0324.
01:25
Okay...
