Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. A
Explanation:
Total number of customers in service A = (250 + 175 + 350) = 775
Average number of customers in service A = 775/3 = 258.33
Total number of customers in service B = (220 + 190 + 240) = 650
Average number of customers in service B = 216.67
Total number of customers in service C = (260 + 200 + 270) = 730
Average number of customers in service C = 243.33
Total number of customers in service D = (245 + 185 + 330) = 760
Average number of customers in service D = 253.33
