Question

a company’s sales manager uses the monthly sales data from the highest 10 performers on the sales team to report that the average monthly sales is $25,784. which statement is true? because the manager uses the monthly sales data from only the highest performers on the sales team, the sales data is biased and not representative of the larger population. because the manager uses the monthly sales data from only the highest performers on the sales team, the sales data is not biased and is representative of the larger population. because the manager uses the monthly sales data from randomly selected members of the sales team, the sales data is biased and not representative of the larger population. because the manager uses the monthly sales data from randomly selected members of the sales team, the sales data is not biased and is representative of the larger population.

Explanation:

To determine the true statement, we analyze sampling bias:

• The manager uses data from only the highest 10 performers (not a random or representative sample of the entire sales team).
• Sampling only the highest performers introduces bias because this group does not reflect the performance of all team members (the larger population).
• Random selection (if done properly) usually reduces bias and improves representativeness, but that is not the case here. The first option correctly identifies that using only top performers creates biased, unrepresentative data. The other options either misstate the sampling method (random vs. top performers) or the resulting bias/representativeness.

Answer:

A. Because the manager uses the monthly sales data from only the highest performers on the sales team, the sales data is biased and not representative of the larger population.
