WebIf the standard deviation of a population is 9, the population variance is: A. WebThe formula for a one-sample t-test can be derived by using the following steps: Step 1: Determine the observed sample mean, and the theoretical population means specified. The sample mean and population mean is denoted by x̄ and μ, respectively. Step 2: Next, determine the standard deviation of the sample, and it is denoted by s. smart life hubitat
