In which service is the average number of customers per city the highest?
Answer & explanation
Correct answer: option 2
Average number of customer of A = \(\frac{250 + 175 + 350}{3}\)
= 258.33
Average number of customer of B = \(\frac{220 + 190 + 240}{3}\)
= 216.67
Average number of customer of C = \(\frac{260 + 200 + 270}{3}\)
= 243.33
Average number of customer of D = \(\frac{245 + 185 + 330}{3}\)
= 253.33
