A large company wants to find out what team-building activity its employees prefer. Which of the following samples can give the most valid generalization?

Question

a group with one member from each department
400 randomly chosen employees from the list of all employees
all 624 female employees in the company
all employees who have worked in the company for 5 years or more

Answer 1

400 randomly chosen employees from the list of all employees

This sample allows for a diverse representation of employees from all departments and levels within the company, providing a more valid generalization of the employees' preferences for team-building activities.

Answer 2

value per house | number of houses
150,000 2
220,000 4
540,000 2
800,000 5
975,000 2

The values of several houses on Mango Street are displayed on the table. What is the median value of these houses?

Answer 3

To find the median value, we first need to list the values in ascending order:

150,000, 150,000, 220,000, 220,000, 220,000, 220,000, 540,000, 540,000, 800,000, 800,000, 800,000, 800,000, 800,000, 975,000, 975,000

There are a total of 17 houses listed, so the median value will be the 9th value:

800,000

Therefore, the median value of the houses on Mango Street is $800,000.
