Answer:
- import statistics
- def st_dev(file_name):
- with open(file_name) as file:
- data = file.readlines()
- numList = []
- for x in data:
- numList.append(int(x))
-
- return statistics.pstdev(numList)
- print(st_dev("text1.txt"))
Explanation:
The solution code is written using Python.
To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).
Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.
We test the function by passing a file which hold a list of integer values in each line (Line 12).

the third answer is correct
Answer:
CHAP
Explanation:
CHAP allows a client to be authenticated without sending credential information across a network.
Answer:
Data resiliency.
Explanation:
Spaces for storage may involve resilience to the information. Selecting a resiliency solution implies whether they assign capacity towards redundant details. The information resiliency choice regarding storage facilities.
Two-way mirror needs two capacity units or more. The information is engraved on both computers. Two-way mirror enables twice the volume of storage assigned to that of the storage capacity as such system capacity. This choice will prevent you against loss of a specific storage unit.
