1. The mean age of employees from School A is: (33+28+36+27+45+23+30+42+48+50)/10 = 35.4 years
The mean age of employees from School B is: (27+26+48+51+49+37+33+35+52+40)/10 = 38.8 years
Therefore, the statement "The mean age of employees from School A is higher than the mean age of employees from School B" is false.
2. The median age of employees from School A is: 33 + 36 / 2 = 34.5 years
The median age of employees from School B is: 35 years
Therefore, the statement "The median age of employees from School A is lower than the median age of employees from School B" is false.
3. The range of ages of employees from School A is: 50 - 23 = 27 years
The range of ages of employees from School B is: 52 - 26 = 26 years
Therefore, the statement "The range of ages of employees from School B is higher than the range of ages of employees from School A" is false.
