PART 1 – 20 PointsThe dataset mpg contains information on miles per gallon (mpg) and engine size for cars sold from 1970 through 1982. The dataset has the features mpg, cylinders, displacement, horsepower, weight, acceleration, model_year, origin, and name.
Load the dataset mpg
Create a new dataframe using the columns weight and mpg
Use matplotlib to make a scatter plot of weight vs mpg labelling the x-axis Weight and the y-axis MPG
If displacement and horsepower were used instead of weight and mpg, the output would be:
displacement horsepower0 307.0 130.01 350.0 165.02 318.0 150.03 304.0 150.04 302.0 140.0.. … …393 140.0 86.0394 97.0 52.0395 135.0 84.0396 120.0 79.0397 119.0 82.0 [398 rows x 2 columns] Part 2 – 20 PointsThe titanic dataset contains data on 887 Titanic passengers, including each passenger’s survival status, embarkation location, cabin class, and sex. Write a program that performs the following tasks:
Load the dataset in titanic.csv as titanic.
Create a new data frame, firstSouth, by subsetting titanic to include instances where a passenger is in the first class cabin (pclass feature is 1) and boarded from Southampton (embarked feature is S).
Create a new data frame, secondThird, by subsetting titanic to include instances where a passenger is either in the second (pclass feature is 2) or third class (pclass feature is 3) cabin.
Create bar charts for the following:Passengers in first class who embarked in Southampton grouped by sex
Passengers in second and third class grouped by survival status
The output should be: survived pclass sex age … deck embark_town alive alone3 1 1 female 35.0 … C Southampton yes False6 0 1 male 54.0 … E Southampton no True11 1 1 female 58.0 … C Southampton yes True23 1 1 male 28.0 … A Southampton yes True27 0 1 male 19.0 … C Southampton no False [5 rows x 15 columns] survived pclass sex age … deck embark_town alive alone0 0 3 male 22.0 … NaN Southampton no False2 1 3 female 26.0 … NaN Southampton yes True4 0 3 male 35.0 … NaN Southampton no True5 0 3 male NaN … NaN Queenstown no True7 0 3 male 2.0 … NaN Southampton no False [5 rows x 15 columns] Part 3 – 20 PointsThe nbaallelo_slr dataset contains information on 126315 NBA games between 1947 and 2015. The columns report the points made by one team, the Elo rating of that team coming into the game, the Elo rating of the team after the game, and the points made by the opposing team. The Elo rating measures the relative skill of teams in a league.
The code creates a new column y in the data frame that is the difference between pts and opp_pts.
Split the data into 70 percent training set and 30 percent testing set using sklearn’s train_test_split function. Set random_state=0.
Store elo_i and y from the training data as the variables X and y.
The code performs a simple linear regression on X and y.
Perform 10-fold cross-validation with the default scorer using scikit-learn’s cross_val_score function.
Ex: If random_state=1 is used, the output is:
The cross-validation scores are [0.08005753 0.06323433 0.0703416 0.06041472 0.07528804 0.06335341 0.07329385 0.06774416 0.06069483 0.07071991]please follow instructions

The class is likely to have students with different exposures to computer programming. You are not required to have any experience in Python. The important issue is how much you learn during our class. DAT 535 Session 1 Programming Assignment Week 1 & 2
Use one Jupyter Notebook file for all parts of the assignment.
Upload your .ipynb file to MyCourses
Part 1 – 20 points Type in these commands one cell at a time and then run each cell.
import seaborn as sns
sns.get_dataset_names () – This will produce the names of the seaborn datasets.
Choose one dataset to print and load. I chose the tips dataset and used the variable name plot.
plot = sns.load_dataset(‘tips’)
print(plot) Create a scatterplot as demonstrated in the Participation Activity Section 2.1.4
Choose your own x a -nd y values from the dataset column names.
Be sure to add some headings and comments to your code as shown at the end of Chapter 2.1
Part 2 – 20 pointsimport numpy as np
Create a one-dimensional numpy array with 9 integer elements. Use dtype ‘int16’
Print the array.
Print the second element of the array.
Use 10 other built in NumPy functions of your choice on the array and print the results.
Part 3 – 20 pointsImport the necessary modules and read in a csv file. The homes dataset contains 18 features giving the characteristics of 76 homes being sold. The modules will be used with the homes.csv file to perform a linear regression. Linear regression will be covered in a different chapter.
Import the NumPy and pandas packages with the aliases used in this material
Import the function LinearRegression from the sklearn.linear_model package
Read in the csv file homes.csv
Ex: If the csv file homes_small.csv is used instead of homes.csv, the output is:
The intercept of the regression is 249.522The slope of the regression is 36.758

i have 2 hours on the timer for my exam, i will send the multiple choice questions here, I need you to send the right answer. the subject is Fundamentals of system management

Question 1:
Compare and contrast the basic personal computer system, the typical smartphone system, and the mainframe computer system in terms of their architecture, capabilities, use cases, and impact on modern computing.
Start by providing an overview of each system, including their hardware components, operating systems, and typical specifications.
Explore the primary use cases for each system. How do these systems cater to different computing needs? Are there any overlapping functions or capabilities?
Analyze the architecture of these systems. What are the key design principles and characteristics that make each system unique? How do these architectures contribute to their performance and functionality?
Question 2:
Examine the fundamental interface components in an average computer system, and discuss their roles, significance, and interactions within the system.
Begin by identifying and describing the core interface components typically found in a computer. These may include the central processing unit (CPU), memory (RAM), storage devices (e.g., hard drives or SSDs), input/output devices (e.g., keyboard, mouse, monitor), and expansion slots or ports.
Discuss the specific functions and roles of each component. For example, what is the primary function of the CPU in processing data, and how does it interact with memory and storage devices?
Analyze the connections and data flow between these components. How do data and instructions travel between the CPU, memory, and storage? What is the role of input/output devices in facilitating user interaction with the computer?
Question 3:
Investigate the role of peripherals and the hierarchy of storage in an average computer system, and analyze how these elements contribute to overall system functionality and performance.
Begin by defining what peripherals are in the context of computer systems and providing examples of common input and output devices. Explain how peripherals enhance the user experience and extend the capabilities of a computer.
Explore the concept of the storage hierarchy in computing. Describe the various storage media and devices that make up this hierarchy, from the fastest and most volatile storage to the slowest but highest-capacity options.

file systems are essential elements of an operating system (OS). Without file systems, it would be impossible to load applications or even to store data files. Whether in the home or in the office, you must understand what it takes to manage storage devices. You should be familiar with what is necessary to prepare devices that enable users to store, manage, and retrieve files. As covered in this unit’s learning materials, there are numerous file systems for each OS. In other words, each operating system supports several compatible file systems.
