When we perform inference about a population mean μ using a t distribution, the appropriate degrees of freedom are found by subtracting 1 ...

We can calculate p̂ and use it as the center of our interval and then add a margin of error above and below p̂ . The experiment of drawing a sample of n objects and cou ...
