We can form a confidence interval for the population total T by finding a confidence interval for the population mean in the usual way,and then multiplying the lower and upper limits the confidence interval by the population size N.

Quizplus · Accepted Answer

This statement is true. To form a confidence interval for the population total, we can first find a confidence interval for the population mean using the usual methods (such as the t-distribution or z-distribution). Then, we can multiply the lower and upper limits of the confidence interval by the population size N to obtain a confidence interval for the population total T. This is because we can estimate the population total T by multiplying the population mean by the population size N.
