R coding stats problem, Tidy data
## Read in the life expectancy data stored at
# http://ismayc.github.io/le_mess.csv and convert it to a
# tidy data frame. Write your code to do this below.
# Make sure to "View" your data to check that it looks like you
expect.

The following table provides data for life expectancy for Batiki
Island.
a. Check students' understanding of the tables with questions
like:
In 1900 to what age did women expect to live?
Was there any year in which life expectancy decreased?
Why do you think there is no data for the years 1940 and
1945?
Comparing just the years 1890 and 1990, has the difference
between the life
expectancies of men and women decreased or increased?
...
4) The table below shows the life expectancy for an individual born in the United States in certain years. Year of Birth Life Expectancy (a) Use the Rossman Chance applet to find the sample correlation coefficient 1930 59.7 1940 62.9 (b) What does the correlation coefficient imply about the relationship between year of birth and life expectancy? 1950 70.2 1965 69.7 (e) We want to know if this data provides strong evidence of correlation between the year of birth and...
Suppose that you have in your possession bivariate data giving birthrate and life expectancy information for a random sample of 15 countries. For each of the countries, the data give both x, the number of births per one thousand people in the country's population, and y, the country's female life expectancy in years. The least squares regression equation computed from your data is y = 84.06 -0.51x. Suppose that you're predicting the female life expectancy for a country whose birthrate...
I am stuck with this coding problem from edx coding python 4.4.6: #This is a long one -- our answer is 20 lines of code, but #yours will probably be longer. That's because it's one of the #more authentic problems we've done so far. This is a real #problem you'll start to face if you want to start creating #useful programs. # #One of the reasons that filetypes work is that everyone #agrees how they are structured.

Before you start For this homework, we will need to import some libraries. You need to execute the following cell only once; you don't need to copy this in every cell you run. In [ ]: import pandas import numpy from urllib.request import urlretrieve from matplotlib import pyplot %matplotlib inline #This library is needed for testing from IPython.display import set_matplotlib_close set_matplotlib_close(False) Introduction In this homework, you will work with data from the World Bank. The subject of study is...
USE R STUDIO The stackloss data frame available in R contains 21 observations on four variables taken at a factory where ammonia is converted to nitric acid. The first three variables are Air.Flow, Water.Temp, and Acid.Conc. The fourth variable is stack.loss, which measures the amount of ammonia that escapes before being absorbed. Read the help file for more information about this data frame. - Give a numerical summarization of each column of the dataset, then use boxplots to help illustrating...

Program: Please read the complete prompt before going into coding. Write a program that handles the gradebook for the instructor. You must use a 2D array when storing the gradebook. The student ID as well as all grades should be of type int. To make the test process easy, generate the grade with random numbers. For this purpose, create a method that asks the user to enter how many students there are in the classroom. Then, in each...
I had tried to work with the
wireshark interface and cannot navigate it due to network problems
and cannot find the question solutions, if any one can help with
detailed steps it would be a great help.
Wireshark Lab #2: Ethernet In this lab, we'll investigate the Ethernet protocol and the ARP protocol. Before beginning this lab, you'l1 probably want to review sections 6.4.1 (Link-layer addressing and ARP) and 6.4.2 (Ethernet) in the text. RFC 826 (ftp://ftp.rfc-editor.org/in- notes/std/std37.txt) contains the...
Question 2 If you read in a csv file using read.csv() function into R, what is the resulting datastructure in which R stores the read-in data? A. numeric B. matrix C. data.frame D. vector Question 3 Suppose you have 4 integers, 4 characters, and 4 logical values. Which datastructure can you use to store all 12 values? Choose one or more options. A. a vector B. a matrix C. a list D. a data frame Question 4 Suppose you have...
I have a data set called ACS that I set my_data <- read.csv('acs_ny_CSV.csv'). One of the values in the data set here is FamilyIncome having a value from 50 to 1 mill plus FamilyIncome Min. : 50 1st Qu.: 52540 Median : 87000 Mean : 110281 3rd Qu.: 133800 Max. :1605000 I need to convert this value to a 0 and 1 as I need to "Make a binary variable with value TRUE for income above $150,000 and FALSE for...
