Question

Quizplus · Accepted Answer

To find the population total, we use the formula: Population Total = Sample Mean x Population Size. Rearranging this formula, we get: Population Size = Population Total / Sample Mean. Substituting the given values, we get: Population Size = Population Total / 400. Solving for the population size, we get: Population Size = 600. Therefore, the population total is Population Size x Sample Mean = 240,000.
