单选题 Fifty applicants for a job were given scores from 1 to 5 on their interview performance. Their scores are shown in the table above. What was the average score for the group?

Score	Number of Applicants
5	2
4	12
3	21
2	7
1	8

A. 2.79
B. 2.86
C. 2.91
D. 2.99
E. 3.03

【正确答案】 B

【答案解析】You can calculate this average score exactly the same way you would calculate a GPA--multiply each of the scores by the number of applicants with that score, add them all up, and divide the sum by 50. 10+48+63+14+8=143;143/50=2.86.
