Sigma unknown calculator
WebThe confidence coefficient is simply the decimal form of the confidence level. So, for example, if the confidence level is 95%, the confidence coefficient is .95. The next step is to solve for α / 2. So, continuing with our example, we would have 1 - α = .95 and find the value of α / 2 to be .025. The most commonly used confidence level is ... http://mathcracker.com/t-tests
