Question (1)
Now,
Lets us p as puppy in the house, and q as i am happy
So,
p : puppy in the house, and q : i am happy
Thus,
The Statements
(i) so if there is a puppy in the house, I feel happy : p -> q
(ii) If I am happy, then there is a puppy in the house : q -> p
(iii) If there is no puppy in the house, then I am not happy. : ~ p -> ~q
(iv) If I am not happy, then there is no puppy in the house : ~q -> ~p
Hence, the statements (i) and( iv) are logically equivalent and statements (ii) and (iii) are logically equivalent.
Question (2)
Let us denote p as i am in school today, and q as i am in CSC231 class, and r as i am in civics class,
So,
p: i am in school today, q: i am in CSC231 class, r: i am in civics class,
Now,
(i) if I am in school today, then I am in CSC231 class :p -> q
(ii) If I am not in school today, then I am not civics class :~p -> ~r
(iii) If I am not in CSC231 class, then I am not in school today :~q -> ~p
(iv) If I am in CSC231 class, then I am in school today : q -> p

Answers
Answer: The statement that accurately reflects how consumers can add more memory to their laptop or PC is: "They can add more internal memory or use an external storage device."
Adding more internal memory, such as installing additional RAM, is a common method of increasing a computer's memory capacity. This can usually be done by purchasing compatible RAM and installing it into the computer's available memory slots.
Alternatively, consumers can also use an external storage device, such as an external hard drive or USB drive, to increase the amount of storage space available to them. While this method doesn't directly increase the computer's internal memory, it does provide additional storage space that can be used to store files and applications.

Describe how the data life cycle differs from data analysis
Answers
The data life cycle and data analysis are two distinct phases within the broader context of data management and utilization.
The data life cycle refers to the various stages that data goes through, from its initial creation or acquisition to its eventual retirement or disposal. It encompasses the entire lifespan of data within an organization or system.
The data life cycle typically includes stages such as data collection, data storage, data processing, data integration, data transformation, data quality assurance, data sharing, and data archiving.
The primary focus of the data life cycle is on managing data effectively, ensuring its integrity, availability, and usability throughout its lifespan.
On the other hand, data analysis is a specific phase within the data life cycle that involves the examination, exploration, and interpretation of data to gain insights, make informed decisions, and extract meaningful information.
Data analysis involves applying various statistical, mathematical, and analytical techniques to uncover patterns, trends, correlations, and relationships within the data.
It often includes tasks such as data cleaning, data exploration, data modeling, data visualization, and drawing conclusions or making predictions based on the analyzed data.
The primary objective of data analysis is to derive actionable insights and support decision-making processes.
In summary, the data life cycle encompasses all stages of data management, including collection, storage, processing, and sharing, while data analysis specifically focuses on extracting insights and making sense of the data through analytical techniques.
Data analysis is just one component of the broader data life cycle, which involves additional stages related to data management, governance, and utilization.

You are working as a marketing analyst for an ice cream company, and you are presented with data from a survey on people's favorite ice cream flavors. In the survey, people were asked to select their favorite flavor from a list of 25 options, and over 800 people responded. Your manager has asked you to produce a quick chart to illustrate and compare the popularity of all the flavors.
which type of chart would be best suited to the task?
- Scatter plot
- Pie Chart
- Bar Chart
- Line chart
Answers
In this case, a bar chart would be the most suitable type of chart to illustrate and compare the popularity of all the ice cream flavors.
A bar chart is effective in displaying categorical data and comparing the values of different categories. Each flavor can be represented by a separate bar, and the height or length of the bar corresponds to the popularity or frequency of that particular flavor. This allows for easy visual comparison between the flavors and provides a clear indication of which flavors are more popular based on the relative heights of the bars.
Given that there are 25 different ice cream flavors, a bar chart would provide a clear and concise representation of the popularity of each flavor. The horizontal axis can be labeled with the flavor names, while the vertical axis represents the frequency or number of respondents who selected each flavor as their favorite. This visual representation allows for quick insights into the most popular flavors, any potential trends, and a clear understanding of the distribution of preferences among the survey participants.
On the other hand, a scatter plot would not be suitable for this scenario as it is typically used to show the relationship between two continuous variables. Pie charts are more appropriate for illustrating the composition of a whole, such as the distribution of flavors within a single respondent's choices. Line charts are better for displaying trends over time or continuous data.
Therefore, a bar chart would be the most effective and appropriate choice to illustrate and compare the popularity of all the ice cream flavors in the given survey.

Explanation:
Need to use Python to create the below function;
''' This function takes as input two lists of same length. It outputs net correlation value between these two lists. To compute correlation between two lists:
1. Compute the average of each list
2. Subtract a list's average from every element in the list (repeat for both lists)
3. Multiply corresponding differences from each list to compute the element-wise correlation
4. Sum all the values from step 3 to compute the net correlation value
Example: [-10,0,10,20],[20,10,10,20] -> 0
def compute_net_correlation(self,data_series_1,data_series_2):
''' #### FILL IN CODE HERE ####
net_correlation = # fill in computation
return net_correlation
Answers
Answer:
The function is as follows:
def compute_net_correlation(data_series_1,data_series_2):
series1 = 0; series2 = 0
for i in range(len(data_series_1)):
series1+=data_series_1[i]
series2+=data_series_2[i]
avg_series1 =series1/len(data_series_1)
avg_series2 =series2/len(data_series_1)
for i in range(len(data_series_1)):
data_series_1[i]-=avg_series1
data_series_2[i]-=avg_series2
data_series_1[i]*=data_series_2[i]
net_correlation = 0
for i in range(len(data_series_1)):
net_correlation +=data_series_1[i]
return net_correlation
Explanation:
This defines the function
def compute_net_correlation(data_series_1,data_series_2):
This initializes the sum of each series to 0
series1 = 0; series2 = 0
This iterates through each data series
for i in range(len(data_series_1)):
This adds series 1
series1+=data_series_1[i]
This adds series s
series2+=data_series_2[i]
This calculates the average of data series 1
avg_series1 =series1/len(data_series_1)
This calculates the average of data series 2
avg_series2 =series2/len(data_series_1)
This iterates through each data series
for i in range(len(data_series_1)):
This subtracts the average from series 1
data_series_1[i]-=avg_series1
This subtracts the average from series 2
data_series_2[i]-=avg_series2
This multiplies the corresponding elements of both series
data_series_1[i]*=data_series_2[i]
This initializes the net correlation to 0
net_correlation = 0
This iterates through each data series
for i in range(len(data_series_1)):
This adds up the corresponding elements of both series
net_correlation +=data_series_1[i]
This returns the net correlation
return net_correlation
As a computer science student, how do you assess your vulnerability to information theft in comparison to a famous celebrity?
Answers
Answer:
Explanation:
As a computer science student, you should assess your vulnerability to information theft by analyzing the types of information you have and where you store it, as well as the security measures you have in place to protect that information. This includes things like passwords, two-factor authentication, and encryption.
A famous celebrity, on the other hand, may have a higher level of vulnerability to information theft due to their high-profile status and the fact that they may have more sensitive information such as financial information, personal contacts, and private photos and videos. They may also be targeted more frequently by hackers and scammers who are looking to exploit their fame and popularity.
It is important to note that everyone's vulnerability to information theft is different and it is important to take the necessary steps to protect your personal information, regardless of whether you are a computer science student or a famous celebrity. This includes keeping your software and operating system updated, being cautious when clicking on links or opening email attachments from unknown sources, and not sharing personal information online.
