4.2.E—Calculate the standard error and margin of error for a sample size for a one-sample t-interval
Calculate the standard error and margin of error for a sample size for a one-sample t-interval.
- The standard error (SE) for a sample mean is given by sSEx = n .
- For a one-sample t-interval for a population mean, the margin of error is the critical value (t∗) times the standard error (SE ), which equals ( * st ){ } | |{ n } . 125 Inference for Quantitative Data: Means UNIT 4
