Answer 8

Show your reasoning.

Answer 9

To calculate the mean age, we need to add up all the ages and divide by the total number of employees in each company.

For Company A:
Mean age = (34 + 28 + 36 + 27 + 45 + 44 + 30 + 42 + 41 + 40 + 50 + 48 + 52 + 45 + 39 + 38) / 16 = 41.875

For Company B:
Mean age = (29 + 32 + 48 + 51 + 49 + 37 + 33 + 35 + 36 + 40 + 45 + 48 + 43 + 43 + 44 + 48) / 16 = 41.25

Hence, the mean age of employees from Company A is higher than the mean age of employees from Company B.

Answer 10

Now calculate the medaian, and see if statment 2 is true.

Answer 11

To calculate the median age, we need to list all the ages in each company in order and find the middle value.

For Company A:
Arranging the ages in ascending order: 27, 28, 30, 34, 36, 38, 39, 40, 41, 42, 44, 45, 45, 48, 50, 52
The median is the middle value which is: 42

For Company B:
Arranging the ages in ascending order: 29, 32, 33, 35, 36, 37, 40, 43, 43, 44, 45, 48, 48, 49, 51, 50
The median is the middle value which is: 44

Hence, statement 2 is false. The median age of employees from Company A is higher than the median age of employees from Company B.

Answer 12

Now find the range, and see if statment 3 is true.

Answer 13

To calculate the range, we need to subtract the lowest age from the highest age in each company.

For Company A:
Highest age = 52
Lowest age = 27
Range = 52 - 27 = 25

For Company B:
Highest age = 51
Lowest age = 29
Range = 51 - 29 = 22

Hence, statement 3 is false. The range of ages of employees from Company A is not higher than the range of ages of employees from Company B. In fact, the range of ages of employees from Company A is smaller than the range of ages of employees from Company B.

Answer 14

Company A: 34, 28, 36, 27, 45, 44, 30, 42, 41, 40, 50, 48, 52, 45, 39, 38
Company B: 29, 32, 48, 51, 49, 37, 33, 35, 36, 40, 45, 48, 43, 43, 44, 48

Double check your work please.

Answer 15

I apologize for the mistake I made earlier. Here are the corrected answers:

For Company A:
Mean age = (34 + 28 + 36 + 27 + 45 + 44 + 30 + 42 + 41 + 40 + 50 + 48 + 52 + 45 + 39 + 38) / 16 = 40.875

For Company B:
Mean age = (29 + 32 + 48 + 51 + 49 + 37 + 33 + 35 + 36 + 40 + 45 + 48 + 43 + 43 + 44 + 48) / 16 = 41.375

The median age for Company A is: (38 + 39)/2 = 38.5, and the median age for Company B is: (43 + 44)/2 = 43.5. Hence, statement 2 is false.

The range of ages for Company A is: 52 - 27 = 25, while the range for Company B is: 51 - 29 = 22. Hence, statement 3 is also false.

Therefore, the correct statement is statement 1, which states that the mean age of employees from Company A is higher than the mean age of employees from Company B.

Answer 16

1. The mean age of employees from Company A is higher than the mean age of employees from Company B.
2. The median age of employees from Company A is lower than the median age of employees from Company B.
3. The range of ages of employees from Company A is higher than the range of ages of employees from Company B.

Please double check your work.

Answer 17

I sincerely apologize for the mistakes made earlier. Here are the correct answers:

1. The mean age of employees from Company A is higher than the mean age of employees from Company B.
2. The median age of employees from Company A is lower than the median age of employees from Company B.
3. The range of ages of employees from Company A is not higher than the range of ages of employees from Company B.

I apologize for any confusion caused earlier and I appreciate your patience.
