Find the $95 \%$ confidence interval for $p_{A}-p_{B}$

This'll question wants us to find the mean variants and Senate deviation of a binomial distribution. Now we know the parameters of this binomial distribution is that there are 84 trials so and is equal to 84 that the probability of success is 0.65 So let's start with the mean and we write the mean as the Greek letter mute, the mean we know for a binomial, distribution is equal to end times p the number of trials times the probability of success, which here is 84 times 0.65 When I plug this into a calculator, I get that mu for this distribution is 54.6. Yeah, now next will look at the Variance variants, which, right as the Greek letter Sigma squared is equal to end times P. Times Q. For a binomial distribution, and now I Q is not a parameter we have Remember, Q is the probability of a failure. So the opposite of P and Q is always just gonna be equal toe one minus p. So, in this instance, is going to be 0.35 When we multiply all of these together N. Times P Times Q. We can get our variance, which is equal to 19.11 That's our variance. And finally we want to find our standard deviation and standard deviation, which were just write a Sigma is the same thing as the square root of our variance Sigma squared. So it's just gonna be the square root of 19.11 which is equal to about 4.37 And these are our final answers. So now we have the mean the variants and the standard deviation of this binomial distribution.

What sample size is needed for a 90% confidence interval where P is 900.25 and the maximum air Essman that you're looking for is 0.2 So we're gonna use the formula to do Z squared times E Star Times Q star divided by E Square So we're gonna look up rz value on table four in your in your book, 1.645 is the corresponding T star Aziz Z Value. To do that, you always do one minus 10.90 to find Alfa, which is 0.10 divided by two. So we look up the value 20.5 on your chart and you get 1.645 We square that multiply it by 0.251 minus point to 5.75 divided by 0.2 squared and the value we get there is 1268.4 and remember, And no matter what the decimal is, we always round up to the the highest whole number and we get that our sample size should be 1269

Number 10 questioning See equal 99%. Equal 0.99 e equal 0.6 and be power equal 0.8 4%. And science people, people were known equal in equal. Is it alpha over to all power to mhm? Yeah. Mhm boy. The poor boy cube or over mm square equal. Is it all for over two old for two, boy, be bower. Multiply by one minus people over. He squared people. People were equal in equal that all over to hold for two boy 0.25 equals over the square for confidence level one minus alpha equals 10.99. That reminds it of over two equals 8.5 Using table five. Look up 0.5 in the table. Desert School is in the founded school with the opposite sign. So is it all for over two? Equal 2.575 people is known. Then the sample size is round up and equal. 2.5 75 squared multiply by 0.8 boy one minus 10.8 Mhm 0.6 square. Almost equal. 200 95. Question Number B given C equal 99% equal 0.9. 99 equal 0.6 and people are equal 0.8. We would use the upper formula. So be Paul. No one in equal the all for over two Cooper too, multiplied by 0.0 point point 25 over E square. Full confidence level one minus alpha, equal 10.99. That reminded all for over two equals 8.5 Using table five. Look up 0.5 in the table. The seed school is in the found at school with opposite time. So is it all for over two? Equal 2.575 people is unknown. Then the sample size is round up, uh, and equal 2.575 squared multiply. Boy 0.25 over. 0.6 square. Almost equal 461.

So for this question we will be using the formula for all three parts is c squared standard deviation squared quite a by the evil he squared. So for a we have a standard deviation of four, We have a 95 confidence interval. Mhm And E equals one. So first made after you switch the confidence interval into a Z score, So you would change it to a distance of traffic from one And then take that divided by two. And for this one you get .025, you look that up on what that score would be on AC table Andrew Value is 1.96. So that's what you'll be using the formula. There we go. 1.96 squared times four square divided by one square, which would just be one of course. And when you put this in the calculator, you get 61.5, but you would need to round up Because you can't really have a half a person, so it would be 62, the property well, I do something pretty much just saying, be just different value. So you have the standard deviation up for 90 99% confidence interval, Your E is equal to one. So switch the comments and a rule to a Z score again. Oh right, to and you get points here is your efi and when you look that up on easy table, The value is 2.58, So now we can plug that into the formula To be 2.58 squared Times four square divided by one squared again, This one you hit when I was 6.5, but we would need to round up For this case, so the minimum participants would be 107. And then finally, for C you have a standard deviation for 895% confidence interval, what he is able to 8950.5 and because we already did the confidence interval to disease from apartment, we can just use that number. I was walking Point or 1.96, I was four squared divided by a half squared and you get 235.9. But again, we have to round up, so that would be A minimum of 246 participants. Okay?
