Employees who are travelling can connect securely to their office network through the internet when a has been established.

The asnwer for this question is: VPN
VPN stands for Virtual private network, which is a form of encrypted network that creates a safe connection to access a certain network.
IT will be a lot harder for hackers to get into VPN connection because VPN could block the data intrusion from the address that is not authorized by the owner.

Explanation:

From the information given:

The population size N = 5

The sample size n = 2

∴

without replacement; the number of possible samples;

=

= 10

Thus, 10 different samples of 2 technicians each are possible.

DIfferent samples

S/No        possible samples          Mean

1                         2   1                         3/2 = 1.5

2                        2   3                        5/2 = 2.5

3                        2   5                        7/2 = 3.5

4                        2   4                        6/2 = 3

5                        1    3                        4/2 = 2

6                        1   5                        6/2 = 3

7                        1   4                        5/2 = 2.5

8                        3   5                        8/2 = 4

9                        3   4                        7/2 = 3.5

10                       5   4                        9/2 = 4.5

                        Total                                30

Sample distribution for the sample mean  

= 3

Population mean =

= 3

Thus, it is obvious that both means are equal
