Assessment 3
Assessment Type: Computer assignment – analysis and 1,500 + 10% word report – individual
assessment.
Purpose: To allow students to demonstrate an understanding of statistical analysis and the ability to
summarise and manipulate sample data, make basic statistical inferences and interpret the results in a
business context. This assessment contributes to learning outcome a, b, c and d.
Value: 25% (Preparation quizzes 5% and Word file, Excel file 20%)
Submission: Preparatory Quizzes — access and submit via Moodle links. An excel file with a unique
dataset and summaries of the dataset. A word file with answers to questions about the summaries of the
dataset and questions about some videos that discuss why statistics is useful.
Task details: Each individual student will be provided with their own unique dataset and they will have to
summarize the dataset using PivotTable and Scatterplot commands using Microsoft Excel
Students will have to use the summaries as the basis of a report that using descriptive and inferential
statistics.
Students will also have to use the dynamic array functions in Microsoft excel to create datasets with
summaries that are like their own unique dataset and describe the relationship between the variables in
simple terms that could be understood by someone that has not done a business statistics course.
Preparatory Quizzes: Before you start summarizing your dataset, you need to do the Preparatory Quizzes
to ensure you are familiar with the concepts and techniques involved. You may attempt the Quizzes as
many times as you like — each new attempt will overwrite the previous attempt. Only the last attempts will
be marked.
Marking Guide: Preparatory Quizzes: worth a total 5% of the final grade – individual marks will be identified
with each quiz in Moodle. Discussion of a sample repot worth 20% of the final grade. The marking rubric is
given on the next page

The popular avenues for publishing a website once it has been built are ISPs (Internet Service Providers), free sites, and web hosting services.

An ISP offers web hosting services in addition to connecting consumers to the internet. As the name implies, free websites let users host their websites on a free subdomain that the website provides. In addition to other services like email accounts and domain name registration, web hosting providers give customers server space on which to host their websites.

Websites can be built using online services, software tools, and plain text editors, but they cannot be published using these methods. Although there are specialised channels for publishing a website, tools and platforms for constructing websites like ASP.NET, Dreamweaver, JavaServer Pages, Nvu, Adobe ColdFusion, and Rapid Weaver do exist.

In the semantic network, the vertex that is connected to all four other vertices (lion, tiger, bear, support, carry) would be the word "bear." Here's an illustration of the semantic network:

    lion

    /  \

bear -- tiger

 |       |

support -- carry

In this network, each vertex represents a word, and the edges represent pairs of words with related meanings. Here's the reasoning behind the connections:

It's worth noting that words can have multiple meanings, and the connections in the semantic network can represent different aspects or senses of those words. In this case, "bear" has connections representing the animal, supporting, and carrying meanings.

The autocorrelation of x(n) = [1 3 -2 4] for 0 ≤ n ≤ 3 is [16, 2, 11, 12]. The autocorrelation function is symmetric around n = 0 because it represents the correlation between the signal and its time-reversed version.

The autocorrelation of x(n) = [1 3 -2 4] for 0 ≤ n ≤ 3 is cxx(n) = [16, 2, 11, 12].

1. In MATLAB, first define the signal x(n):
```matlab
x = [1 3 -2 4];
```

2. Use the 'xcorr' function to calculate the autocorrelation of x(n):
```matlab
cxx = xcorr(x);
```

3. By default, 'xcorr' calculates the autocorrelation for the full range of possible lags. To get the values for 0 ≤ n ≤ 3, you need to extract the last 4 values of the result:
```matlab
cxx = cxx(end-3:end);
```

4. To plot the autocorrelation versus lag, use the 'stem' function:
```matlab
lags = 0:3;
stem(lags, cxx);
xlabel('Lag');
ylabel('Autocorrelation');
title('Autocorrelation of x(n)');
```

Now, for the second part of your question: cxx(n) = cxx(-n) because the autocorrelation function is symmetric around n = 0. In other words, cxx(n) represents the correlation between the signal and its time-reversed version, so it has the same value when n is positive or negative.

The autocorrelation of x(n) = [1 3 -2 4] for 0 ≤ n ≤ 3 is [16, 2, 11, 12]. The autocorrelation function is symmetric around n = 0 because it represents the correlation between the signal and its time-reversed version.

Functions are pre-written formulas that perform calculations using specific variables, also known as inputs, in a predetermined order or structure. Functions can be used to do calculations of any complexity. The Formulas tab on the Ribbon contains the syntax for all of Excel's functions.

Answer:

In a broadcast network such as radio network for example a walkie talkie, the broadcasted transmission is received equally by all receivers indiscriminately which may lead to dissemination of classified information to an unauthorized receiver, therefore, the network layer is required is needed to ensure proper routing of the information

Similarly, when the all the broadcasters in one location are each trying to send messages to different receivers at another given location, there would be potential for network congestion and it would be difficult to send information through the network

When there is need for priority service the presence of a network layer is needed in the network

However, when the above functions performed by the network layer is not required, then, the network layer can be excluded, such as the communication between layers 4 - 7 of the OSI model

To develop a system that reads character values from the user and store them in a 2D array of size [2][3], and then find how many times the letter ‘a’ occurred and print the 2D array as a matrix, we can use the following code:```#include
#include

int main()
{
   char arr[2][3];
   int i, j, count = 0;

   for(i=0; i<2; i++)
   {
       for(j=0; j<3; j++)
       {
           printf("Enter a character: ");
           scanf(" %c", &arr[i][j]);
           if(arr[i][j] == 'a' || arr[i][j] == 'A')
              count++;
       }
   }

   printf("\nThe 2D array as a matrix is:\n");

   for(i=0; i<2; i++)
   {
       for(j=0; j<3; j++)
       {
           printf("%c ", arr[i][j]);
       }
       printf("\n");
   }

   printf("\nThe letter 'a' occurred %d times in the 2D array.", count);

   return 0;

}```Here, we have declared a 2D array of size [2][3] to store the character values entered by the user. We have used two for loops to iterate over the array and read the character values entered by the user. We have also used a counter variable to count the number of times the letter 'a' occurred in the array.Once we have read all the character values, we print the 2D array as a matrix using another set of for loops. Finally, we print the number of times the letter 'a' occurred in the array.

The method's return type in the given code is identified by the term "void".

The return type of a Java method is specified just before the name of the method. In this case, we have a method called main, and its return type is indicated by the keyword void, which means that the method does not return any value.

So, the correct answer to your question is option d: void. Options a, b, and c do not specify the return type of the method.

Additionally, there is a syntax error in the given code. The correct syntax for defining a class and its main method in Java is as follows:
