arithmetic test is given twice within a few days to a student. The highest possible score is 40. He receives a score of 35 the first time and a score of 18 the second time. If similarly varying results are obtained from other students, the test result is probably unreliable in the idea o

Answers

Answer 1

Similar varying results obtained as scores from other students indicates that the test is; Unreliable.

This is about test reliability and it is based on consistent results. This implies that it is a measure of how well a characteristic of a test is measured dependably or consistently.

With reference to the above on test reliability, applying it to our question. If the student took the test twice and got a similar result the two times, then the test is said to measure the score reliably but if the two scores are not similar but vary widely from each other, then the test is said not to measure the score consistently and is said to be unreliable.

In our question, since varying results scores are continually obtained for two same tests of same students, then we can say the test does not measure the scores reliably and we can conclude that the test is unreliable.

Emma, the quality control manager in a software development company, asks the testing team to check whether the user interface is friendly. To which type of testing is Emma referring?
A.
usability testing
B.
data comparison
C.
validation testing
D.
stress testing
E.
destruction testing

Answers

Answer: A. Usability testing
Explanation:
Usability testing would be the correct answer because if the user interface isn't "frendly" then people won't be able to use it properly. Or if you are refering to the word friendly as looking safe, then even more so would be usability testing. Because if people don't like the fonts and styles of the user interface, they might not use it at all.

5) Write a program to read text to end-of-file, and print a count of word lengths, i.e. the total number of words of length 1 which occurred, the number of length 2, and so on. Define a word to be a sequence of alphabetic characters. You should allow for word lengths up to 25 letters. A typical output should be like this: length 1 : 10 occurrences length 2 : 19 occurrences length 3 : 127 occurrences length 4 : 0 occurrences length 5 : 18 occurrences

Answers

Answer:

Explanation:

The following code is written in Python. It is a function that takes in the name of the file to be read and the size of the word. Then the function reads the file, removes whitespace and commas, splits the text into words, and scans the words for all the words that have the same length as the number passed. It counts all those words and prints out the number of occurrences of words of that length.

def countOccurrences(file_name, word_size):

   f = open(file_name, 'r')

   text = f.read()

   text = text.replace(',', '')

   split_text = text.split(' ')

   occurrences = 0

   for word in split_text:

       if len(word) == word_size:

           occurrences += 1

   print("Length 1: " + str(occurrences) + " occurrences")

The aim of this activity is to implement an algorithm that returns the union of elements in a collection. Although working with sets is quick and easy in Python, sometimes we might want to find the union between two lists. Create a function called unite_lists, which uses a loop to go through both lists and return common elements. Do not use the built-in set function.

Answers

Answer:

The function in Python is as follows:

def unite_lists(A, B):

   union = []

   for elem in A:

       if elem in B:

           union.append(elem)

   return union

Explanation:

This defines the function

def unite_lists(A, B):

This initializes an empty list for the union list

   union = []

This iterates through list A

   for elem in A:

This checks if the item in list A is in list B

       if elem in B:

If it is present, the item is appended to the union list

           union.append(elem)

This returns the union of the two lists

   return union

What information will you find in the 16-bit field in an IP datagram?

Answers

Answer: This 16-bit field defines the entire packet size in bytes, including header and data. The minimum size is 20 bytes (header without data) and the maximum is 65,535 bytes. All hosts are required to be able to reassemble datagrams of size up to 576 bytes, but most modern hosts handle much larger packets.

Explanation: Hopefully this helps you with what ever u are doing.

An information which you will find in the 16-bit field in an IP datagram is: the total length of the datagram it's attached to.

An IP address is an abbreviation of internet protocol address and it can be defined as a unique number assigned to a computer or other network devices such as routers, switches, etc., in order to differentiate each device from one another in an active network system. Thus, an IP address is typically used to uniquely identify each computer or network device connected to the internet or an interconnected network.

In Computer networking, IP address are classified into two (2) main categories and these are;

Local (internal) IP address.Global (external) IP address.

An IP datagram can be defined as the standard format of data that an internet protocol (IP) recognizes.

Generally, an IP datagram comprises two (2) main components and these include:

1. The header: it is used for sending messages on a computer to the protocol in the same layer of a destination (recipient) computer.

2. The data: this is a set of information that is transmitted from one computer to another over an interconnected network.

On a related note, an IP datagram contain three (3) fields which are typically used for the transmission of data;

Header length.IP version.Total length.

The Total length is a field that is used to specify the total length of an IP datagram and it is typically 16-bits in size.

In conclusion, an information which is found in the 16-bit field in an IP datagram is the total length of the datagram it's attached to.

Write a program that computes the sum of squares for a sequence of positive whole numbers. The program asks the user to enter the starting number. Then it asks the user to enter an ending number. It computes the square for each number from the starting number to the ending number. It also calculates the sum of these squares. It displays the numbers, their squares and the sum of the squares.

Answers

Answer:

In Python:

start = int(input("Start: "))

end = int(input("End: "))

total = 0

print("Number\t Squares")

for num in range(start,end+1):

   print(num,"\t",num**2)

   total+=num**2

print("Total: ",total)

Explanation:

This gets the starting number

start = int(input("Start: "))

This gets the ending number

end = int(input("End: "))

This initializes total to 0

total = 0

This prints the header

print("Number\t Squares")

This iterates through start to end

for num in range(start,end+1):

This prints each number and its square

   print(num,"\t",num**2)

This calculates the total squares

   total+=num**2

This prints the calculated total

print("Total: ",total)
