SP and Enrich are water pump manufacturers. SP claims that its water pumps have a higher maximum discharge flow rate than Enrich water pumps with the same specifications. To test the claim, a consumer bureau selected 10 water pumps from each manufacturer by visiting the
distribution sites of both SP and Enrich and blindly selecting one water pump from 10 different lots at their sites.
The consumer bureau found that, on average, SP water pumps had a 4% higher maximum discharge flow rate than Enrich water pumps.
Given the bureau's data collection method and report, what conclusion can be made?

A. The collection method was random because the selection process ensured a random representation of each manufacturer's
water pumps

B. The collection method was unfair because SP's claim may have influenced the bureau's report

C. The collection method was fair because SP water pumps had the higher maximum discharge flow rate.

D. The collection method was nonrandom because only 10 water pumps from each manufacturer were selected.
