An approximate confidence interval for a population mean is calculated based on a sample size of 16 and is found to have width, $w$ . A second confidence interval is calculated from another sample with the same sample standard deviation. Given that the same $z$ -value was used for both intervals and the width of the second interval is $2w$ , what is the size of…
