Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like <em>f(x)=</em> <em>23y-5 </em>(that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise. <em />

What sample size is needed to give a margin of error within plus-or-minus 5% in estimating a population proportion with 90% conf
VARVARA [1.3K]

Answer: 271.

Step-by-step explanation:

When the prior population proportion of success is not available, then the formula to find the sample size is given by :-

n=00.25(\dfrac{z_{\alpha/2}}{E})^2

Given : Significance level : \alpha: 1-0.90=0.1

By using the standard normal distribution table ,

Critical value : z_{\alpha/2}=1.645

Margin of error : E=0.05

Then , the required minimum sample size will be :-

n=0.25(\dfrac{(1.645)}{0.05})^2=270.6025\approx271

Hence, the required minimum sample size is 271.
