If the lower and upper confidence limits of the population mean $\mu$,using a sample of size 100,are 225 and 280,respectively,then the lower and upper confidence limits of the total of a population of size 3000 are respectively
A) 652,500 and 812,000
B) 675,000 and 840,000
C) 697,500 and 868,000
D) 652,862 and 812,452

Question

Quizplus · Accepted Answer

The confidence limits for the total population are calculated by multiplying the confidence limits of the mean by the population size: 225 * 3000 = 675,000 and 280 * 3000 = 840,000.
