Data Analysis: Dabdub’s Email
ME 182 - Winter 2022
Each entry in the data is a Unix time stamp indicating the date and time when an email was received
in one of my email accounts. This project is the analysis of such data.
Read all the data files into R and create ONE data frame that looks
exactly
as shown below. You
might have to first convert to .csv

Note that in order to complete the task, you will need to use functions that were not discussed in
class. Expect that. In part, the purpose of the project is to test your ability to find answers in a
completely independent approach.
For the rest of the assignment you might need to make changes (e.g., factor, perform time conver-
sions, etc) to the data frame.
Investigate the effect of the day of the week on the amount of email received. Create a plot that
shows the total emails received per day of the week.
Investigate the time of the day that emails are received each day of the week. Create a box plot
that shows distribution of hour for each day of the week.
Investigate the time when people send email. Create a plot that shows the number of emails received
at a given hour for a given year. Use the facet feature to show data for the last 6 years.
Impact of Covid. Create a plot that shows the number of emails received in a given month for a
given year. Use the facet feature to show data for the last 6 years.
Investigate the month in more detail. Create a bar plot that shows the total number of emails for
a given month for the entire data. You can color the bar using the hour of the day that the email
was received.
Get creative. Is there another kind of plot that would be insightful?
Excellent Work!
That is it. You are done.

I’m using this code in MATLAB but for some odd reason every time I run it on MATLAB I keep on getting a different graphs.

For the Following question Graph all 4 : [I just need all 4 graphs and please explain and make clean solution]
Position vs time
Velocity vs time
Acceleration vs time
Force vs time
[For your convenience, I have solved the numerical solutions for the problem] (Please Look at the picture since it is much cleaner)
Question : A 550 kilogram mass initially at rest acted upon by a force of F(t) = 50et Newtons. What are the acceleration, speed, and displacement of the mass at t = 4 second ?
a =(50 e^t)/(550 ) [N/kg]
v = ∫_0^t▒(50 e^t )dt/(550 )= v_0 +(50 e^t-50)/550=((e^t- 1))/11
x = ∫_0^t▒(e^t- 1)dt/(11 )= x_0 +(e^t- t - 1)/(11 )
a(4s)=(50*54.6)/550= 4.96[m/s^2 ]
v(4s)=((e^4-1))/11= 4.87[m/s]
x(4s)=((e^4- 4 - 1))/11= 4.51 [m]

Could you change the code so that it looks like the graph that you see on the picture using MATLAB, please send the code when you are finished. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Fix the random seed for reproducibility rng(45); % Assumed positions of cars CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves pDiesel = polyfit(carPosition, CO2Diesel, 3); pPetrol = polyfit(carPosition, CO2Petrol, 3); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Plotting the data figure; hold on; scatter(carPosition, CO2Diesel, 'o', 'MarkerEdgeColor', [1 0.5…arrow_forwardI need a MATLAB code that uses image segmentation to take this photo and single out the weeds in the yard. It also needs to calculate the number of pixels/percentage of the pixels that are in the weeds. Please provide notes in the lines as well so it is easy to follow and understand. Thank you for your help!arrow_forwardCould you please fix my code it’s supposed to look like the graph that’s on the picture. But the lines do not cross eachother at the beginning. Could you make the lines look like the lines on the graph? Use this code in MATLAB and fix it. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Define your seed here seed = 50; rand('seed',seed); % Set the seed for reproducibility % Assumed CO2 emissions for Diesel and Petrol CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves with a reduced degree of 2 pDiesel = polyfit(carPosition, CO2Diesel, 2); pPetrol = polyfit(carPosition, CO2Petrol, 2); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Plotting the data figure; hold on; % Plot Diesel best fit line…arrow_forward
- I need help with the purple line the line that you see one the graph on the picture needs to be on the graph. Use this code to add the purple line and make sure it’s crossing the orange line. Please make sure the lines are positioned the same way it is shown on the picture with the graph. Use this code on MATLAB and add the purple line. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Use the 'seed' function instead of 'rng' seed = 50; % Define your seed here rand('seed',seed); % Assumed CO2 emissions for Diesel and Petrol CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves with a reduced degree of 2 pDiesel = polyfit(carPosition, CO2Diesel, 2); pPetrol = polyfit(carPosition, CO2Petrol, 2); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition);…arrow_forwardHi I need help to make the line change into a different color, I half of the line to be orange and I need the other half of the line towards the end to be purple as shown in the picture. Also I need there be a box saying Diesel, petrol, diesel best fit, petrol best fit. This part is also shown in the graph. Please use this code and fix it in MATLAB: % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Fix the random seed for reproducibility rng(50); % Assumed positions of cars CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves pDiesel = polyfit(carPosition, CO2Diesel, 3); pPetrol = polyfit(carPosition, CO2Petrol, 3); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Combine the best fit lines combinedFit =…arrow_forwardCreate an illustration or diagram of the amusement park ride called THE BUMPER CAR RIDE, then proceed to add labels based on the guidelines provided within the image.
