Code using R or Python

We observe from our campus the temperature and count the number of squirrels. Our observations are

T = [52, 52, 50, 54, 50, 52, 54, 80, 80]

Sq = [8, 10, 6, 9, 6, 12, 12, 1, 0]

a) What is the covariance of these vectors? (1point)

b) What is the covariance matrix? (1point)

c) What is the correlation coefficient? (1point)

d) Find the coefficient of determination? (1point)

e) Can you make any statement or conclusion given these numbers as to the relationship of these paired observations? (1point)

f) If we try to fit a straight line model to these variables; What is the best choice 1 for the dependent and independent variable and why? What is the slope β1 ? What is the intercept value β0 ? (show your working) (4points)

g) Which aspect of the data is not being captured and does this affect the methodology of the straight line model used? (2points)

h) What is a good measure to assess the quality of the straight line fitted above? Use this measure. (1point)

In python Using the example code from the HangMan program in our textbook, create a Word Guessing Game of your choice. Design a guessing game of your own creation. Choose a theme and build your words around that theme. Keep it simple. Note: I would highly recommend closely reviewing the HangMan code and program from Chapter 10 before starting work on this project. You can run the program via my REPL (Links to an external site.). Using python Similar to...

"PYTHON" Write some code " USING PYTHON" to keep reading numbers from the user until the users enters a negative number. The program then prints out: a) the sum of all the numbers b) the average of all the numbers c) the max of the numbers d) the min of the numbers Note we did not cover lists (array) so you will not use them in this problem. Finally, ask the user for their name, then print their name as...

This is using Python, it is utilizing code from a Fraction class to create a Binary Class Please leave comments so I may be able to learn from this. Instruction for Binary Class: Exercise 6.18: Design an immutable class BinaryNumber, in the style of our Fraction class. Internally, your only instance variable should be a text string that represents the binary value, of the form '1110100'. Implement a constructor that takes a string parameter that speciﬁes the original binary value....

Given a string, such as x = ‘itm330’, write a Python program to count the number of digits and the number of letters in it. For example, in ‘itm330’, there are 3 letters and 3 digits. Hint: Very similar to page 11 on the slides. To check if a character c is a digit, use c.isdigit(). If c is a digit, c.isdigit() will be a True.
