The correct answer is: statements 1 and 2
1. The mean age of employees from Company A is higher than the mean age of employees from Company B:
Mean age of Company A = (34+28+36+27+45+44+30+42+41+40+50+48+52+45+39+38) / 16 = 39.44
Mean age of Company B = (29+32+48+51+49+37+33+35+36+40+45+48+43+43+44+48) / 16 = 41.81
Therefore, the mean age of employees from Company B is higher.
2. The median age of employees from Company A is lower than the median age of employees from Company B:
The median age of Company A is 40.
The median age of Company B is 43.
Therefore, the median age of employees from Company A is lower.
3. The range of ages of employees from Company A is higher than the range of ages of employees from Company B:
Range of Company A = 52 - 27 = 25
Range of Company B = 51 - 29 = 22
Therefore, the range of ages of employees from Company A is higher.
So, the correct statements are 1 and 2.
