The correct answer is: statements 2 and 3
Explanation:
1. The mean age of employees from Company A is 41.8 (mean = sum of all ages / number of ages) and the mean age of employees from Company B is 40.6. Therefore, statement 1 is false.
2. The median age of employees from Company A is 40.5 (median = middle value when arranged in ascending order) and the median age of employees from Company B is 43. Therefore, statement 2 is true.
3. The range of ages of employees from Company A is 25 (range = max age - min age) and the range of ages of employees from Company B is 22. Therefore, statement 3 is true.
