This statement is true. To find a confidence interval for the population total T, we can find a confidence interval for the population mean in the usual way (using the sample mean, standard deviation, and sample size), and then multiply the lower and upper limits of the interval by the population size N to obtain the lower and upper limits of the interval for the population total.
