A、The median age of the full-time employees in the 30-41 age-group in 2017 was 35.5 years.

C、In 2017, the number of part-time employees over age 50 was greater than the number of full-time employees over age 50.
答案
B
解析
选项A: 由于没有具体数据,无法计算中位数,错误。选项B:2005年全职和兼职的比例为(150+192+153)/(202+248+190)=495/640=0.77,2017年比例为(190+235+182)/(215+258+208)=607/681=0.89,增加了,正确。选项C:从大于42岁的数据中无法判断大于50岁的数据,错误。
