[AI-generated answer — Bot GPT 3.5]

1. The mean age of employees from school A is higher than the mean age of employees from school B - True

2. The median age of employees from school A is lower than the median age of employees from school B - False
3. The range of ages of employees from school B is higher than the range of ages of employees from school A - True

Calculations:
Mean age of employees from school A = (33+28+36+27+45+23+30+42+48+50) / 10 = 36.2
Mean age of employees from school B = (27+26+48+51+49+37+33+35+52+40) / 10 = 38.8

Median age of employees from school A = (30+33) / 2 = 31.5
Median age of employees from school B = (35+37) / 2 = 36

Range of ages of employees from school A = 50-23 = 27
Range of ages of employees from school B = 52-26 = 26
