Can we say that the why sort omitted is effective. So this is the confidence interval of the population proportion the last. Whose airplane? Nine 302 Than my necessary zero 162 on the left. At this point we can write the interrupt the confidence interval of the proportion.
And here the arrow impair this in for the small places becomes 0.0162. Yeah thou us 0.9302: 1 -0.930 to all over the total which is 945. Now that is 97.5 which corresponds with one point nine here And also the last 0.061 day You can have it as 1.96 Crisco value at this point we can have error. And to find the out to find 97.5 we would look at the table. An area which covers 97.5% to the left of the hole. Okay so it means that we have an area which is so 97.5 percent. So if you divide that by two we have 0.0. Which we have calculated Then one mine is the pee all over the Turo Though we have 95% confidence level.
Okay so the second path we would Use the data to construct 95% confident interval for the proportion with this one will need the error which is equal to the critical value. So that's the the best point estimate for the population proportion. But mm and that is the number of the web girls all over there. The first part that we are solving we are looking at the best estimation of the proportion. And we are looking at uh The confidence level. The number that way girls that's eight 7 9. In this lesson we have the following data.
