Category: Mathematics Homework Help

This are technical calculations for quantum mechanics. The workings should be shown well in the solution document. Total words should be 2900. consider that. attached are the questions which need to be solved.

I’m working on a probability question and need guidance to help me understand better.

1. QUESTION:
Describe the sample space and all 16 events for a trial in which two coins are thrown and each shows
either a head or a tail.

2. QUESTION:
A fair coin is tossed, and a fair die is thrown. Write down sample spaces for
(a) the toss of the coin;
(b) the throw of the die;
(c) the combination of these experiments.
Let A be the event that a head is tossed, and B be the event that an odd number is thrown. Directly
from the sample space, calculate P(A ∩ B) and P(A ∪ B)

Help me study for my Statistics class. I’m stuck and don’t understand.

I have attached the questions below, i just need help and explanation on how to solve these.

See attached image for question #1

2) Use the information from problem 1. Perform a complete test of the hypothesis that the population
correlation coefficient (ρ) is 0. Show all steps (note – obviously this should be a one sided test! Make sure you
know why!).

3) Now let’s assume you wanted to predict weights from heights. In other words, now let’s use the same data
from problem (1) and do a regression instead.

(a) Calculate b0 and b1.

(b) Carefully draw your least square regression line on the plot you made in 1(a). (Don’t just “sketch”,
be a little careful).

4)

(a) Now do a significance test of H0: β1 = 0. Show all your calculations (including your residual
calculations). Again, note that this should be a one sided test (why?).

(b) Compare your t
*
from 4(a) with your t
*
from problem 2. Are they the same? This is not a coincidence,
although once you do more complicated analyses, you can’t rely on this “equivalence”.

This is an easy exercise in math and I need someone to help me with

Section 1.1 + 1.2 + 1.3

Also, I’m searching for someone who can help me with the whole semester, if you were good enough at this assignment I will do the rest of the work with you, I will be your customer.

Read homework directions carefully. If directions state technology should be used or that technology formulas should be written those parts may be skipped as you are not required to have a graphing calculator for this course. Any graphing should be done by hand using a well-labeled coordinate grid.

**Don’t forget your heading and to show ALL work per problem to earn credit. Use of computer programs like Microsoft Excel or graphing calculator shortcuts are not permitted

Progress Check

Use this activity to assess whether you and your peers can:

• Use a five-number summary and a boxplot to describe a distribution.
• Recognize the median as the center between two equally-sized groups within a distribution of data.
• Use the IQR to describe the spread for the middle 50% of a data set.
• Recognize the limitations of a boxplot.

Context

Here is a boxplot for a distribution of data.

Prompt

1. Calculate the IQR for the boxplot shown.
   
2. Make up a data set (n = 10) that has the same minimum value, same median, and same maximum value, but a larger IQR than the boxplot shown. List your data set and then describe your strategy.
3. Make up another data set (n = 10) that has the same minimum value, same median, and same maximum value, but a smaller IQR than the boxplot shown. List your data set and then describe your strategy.

Hello Paul, hope you are doing well. You agreed to help me with my practice final which will be on May 24th, from 6pm-8pm (New York time), I hope you are still available to help. I am officially posting this question now ahead of time which will hopefully make it easier for us to interact and both of us to prepare, as I may have some questions for you while I study, I hope that is OK with you. My final is on the 29th, so that gives me four days to prepare after the practice final. As before I only need you to answer the questions I provide one by one, and a copy of your work for each question at the end of the assessment. The final will be on sections 2.2-5.5 from the textbook Single Variable Calculus, Early Transcendentals by James Stewart,8th ed Cengage Learning ISBN:9781305270336. The practice will be very similar to the official, so if you could offer advice on what to focus on in terms of studying and reviewing after helping me with it, I would greatly appreciate it. Let me know if there is anything you need.

For learning exercises 30.5. Do 3,4 and 5 . You can do 3 and 4 by using technology. It is a lot easier. Do not do by hand. For learning exercises 30.6 do 2 , 11, and 12. I will send you our class material. It might help you.

will have four questions similar to the practice, please write details step so I can easy understand

given practice question and lectures

will send solutions to the practice tomorrow

instructions: Homework 1 needs to be completed using RMarkdown please read through the other materials to help you answer the questions for the homework. Pls save the RMarkdown file as a pdf when you are done! The second part of the homework is a journal. Journals are to encourage responsible consumption of statistics “in the wild” and understand how methodologies might be used in various settings, we will be reading or viewing news articles, podcasts, videos, etc. This content comes from a variety of nationally recognized and credible news outlets and will be posted on Moodle. Your journal entries should be written in response to this content.Journal entries will be worth 15 points each. I will post questions to help guide your responses. To receive full points for your journal, you must engage with the material beyond simply answering the questions–for instance, how does the article clarify topics we’ve learned in class? How did it affect you? Do you have personal connections to any of the material? Did this article make you rethink your own position or habits? I have chosen to do option 1 for the journal please follow the instructions mentioned aboved for the journal entry i also have attached the article for option 1 that you will need to read in order to do the assignment. Please send the homework assignment as a pdf from RMarkdown and the journal entry as a word document these should not be saved all in one document thanks!
