Find and record the pulse rate of 10 different people where you work. Tell us a little about the population from which you drew your data.  I collected the following data…radial pulse rates 54, 62, 63, 72, 75, 77,80, 83, 96, 112.  My co-workers that I received my data from range from 24-year-old healthy, fit runner to a 64-year-old who is 2 months away from retirement.  The data came from colleagues that are nurses, a house keeper, resident doctors, unit secretary, and a surgical technician.   Describe your findings in terms of central tendency and variability. Consider using some of the following to help you form your initial discussion post: What are your measures of central tendency (i.e., mean, median, and mode)? Which might be the better measure for central tendency and why? What is the standard deviation of your data? How variable are the data (range)? Are there any outliers? Investigate possible reasons for these outliers, and things that might limit them if further study were to be carried out. What are some variables that should be considered in discussing your measures of central tendency and variation? Is there any skewness in your measured data? How would you describe this data (i.e. what insights did you gain from this data)?

Mid Term Paper: You will write a paper in proper APA format, including a title page, be double spaced in 12 pt. font, and include citations. The Greed Cycle” on page 175-185 will be presented. The paper should be between 3-5 pages excluding the title and reference pages. Your answers must make an argument and support it with ethical and logical arguments. You must use a robust amount of course material and facts from the case study to support your answers. Make sure you support your answers with facts, not opinions. The following three questions will need to be answered. A. Do you agree that investors and executives are too greedy OR do you think this is just capitalism at work? Should there be changes? If so, what? If not, why? B. Do the issues discussed by Cassidy denote deep, permanent flaws in our corporate system? Explain your stance. C. What effect has the “greed cycle” discussed by Cassidy had on the rest of the economy and on our society? Can we avoid future greed cycles or are they an inevitable part of our system?

Hello I just need a 2 page paper about George Boole the mathematician. My professor is not very strict so just a normal paper about the history of George Boole will do.

When grading math papers, the teacher often has to treat the student’s solutions like a puzzle that needs to be unravelled. You have no clue what they are doing or why. Students rarely write down numbers or scratch work at random, there is some kind of logic to it. Your job as the teacher is to figure out what that logic is, pinpoint the errors, and then come up with a way to fix it. View the following lecture to learn about the process of error analysis which explains what it is, how to use it and then presents many examples of common student errors.

1. Why do we want our standard deviation to be low for our sample? 2. There are tons of reasons why our sample’s time completing their rental task differed from the website’s claim. There are other reasons for why the differences occur. All out test tells us is that the sample and population differ. As a Pause Problem, tell me two more! 3. Here is a three part question. First, write out in words a research hypothesis for this statement: The Geography Department is interested in finding out if the average GPA of this year’s graduating seniors is comparable to the average GPA of graduating seniors over the last 40 years. Second, write the formula of the null hypothesis for the above research problem. Finally, write the formula of a directional or non-directional research hypothesis for the above research problem.

Course: College Algebra You will need to complete 15 math problems that I will send to you ONE HOUR BEFORE the due date. Solve each problem on paper (NEATLY AND LEGIBLY) and submit a picture of it once completed. YOU MUST SHOW ALL OF YOUR WORK for each problem. You will only have ONE HOUR to complete the assignment. You will not be able to see any of the questions earlier than 1:00 PM and everything must be answered correctly by 2:00 PM at the latest. The questions will NOT be on chegg, quizlet, or any other site. ******ALL answers MUST be 100% CORRECT. Please DO NOT bid unless you have a clear understanding of the following topics and can complete the assignment in 1 hour or less****** The following topics will be on the assignment: Chapter 5 Systems of linear equations Section 5.1: Systems of Linear Equations: Section 5.2: Matrix solutions to systems Section 5.3: Determinant Solution of Linear Systems Section 5.4: Partial Fractions Section 5.5 Nonlinear Systems of equations Section 5.6 Systems of inequalities Section 5.7 Matrices and Matrix Operations Chapter 6 Analytic Geometry Section 6.1 Parabolas Section 6.2 Ellipses Section 6.3 Hyperbola KEEP IN MIND: – Write LEGIBLY – Show ALL of your work – 15 questions – 1 HOUR MAX – CORRECT ANSWERS ONLY

Z-scores A normal distribution of scores has a standard deviation of ? =10; and a ? = 70. Find the z-scores corresponding to each of the following values: a) A score that is 20 points above the mean. (Hint: what score is 20 points above the mean of ? = 70?) b) A score that is 10 points below the mean. c) A score of x = 50. d) A score of x = 35.

Calculating Confidence Intervals The purpose of this assignment is to practice calculating confidence intervals. For this assignment, students will utilize Excel and SPSS Statistics and the “Example Dataset.” Using the “Example Dataset,” complete the following: Based on a normal distribution curve, calculate the probability of an individual being 60 years or older in this population. Show the Excel and SPSS formulas or your hand calculations. Include screenshots as needed to illustrate this. Using the sample standard deviation of age as an estimate of the population standard deviation, calculate by hand the standard error of the mean. Show your calculations and the answer. Calculate by hand a 95% confidence interval for “Age” based on the sample mean. Use SPSS to verify your answer. Include your calculations and screenshots of the SPSS output. Interpret the confidence interval for age and explain the three pieces of information needed to calculate a confidence interval. Submit one Word document that includes all of the assignment deliverables. APA style is not required, but solid academic writing is expected.

For this assignment, you will analyze three questions that have been solved by a student. Each example has one error in the solutions. Copy and paste the questions into the discussion board and write a note to the student of what the error is for each example. When correcting each student, be specific as to what was wrong for each case. Example 1: Complete the first month’s charges and find the balance for Month 2. The APR is 15.99% with a minimum payment of 5%. The carry-over balance is $500. Student Answer: Month Carry-Over Balance Finance Charge New Balance Minimum Payment 1 $500 $6.66 $506.66 $25.33 2 $474.67 XXXXXXXX XXXXXXX XXXXXXXXX Example 2: What exact excel formula is needed to find the monthly payment for a house that costs $90,000? The APR is 4.5% for a 30-year loan. Student Answer: =PMT(4.5/12,30*12,-90000) Example 3: Using Excel, what formula is needed to find the total loan amount for a new car? You can spend $180 each month on payments and the loan rate is 5.72% for 4 years. Student Answer: =PV(.0572/12,4/12,-180) **MUST PLEASE USE EXCEL FOR ASSIGNMENT**

Normal distributions can be used for many purposes. One purpose might be to determine warranty times on a new game system. Consider if game systems normally last for 36 months before a failure of some sort with a standard deviation of 5 months. If we wanted to have a warranty that paid off on only 5% of the machines (in other words where 95% of them will work) then we could use: =NORMINV(0.95,36,5) which would give 44.22 months. This means that we should set our warranty period at 44 months to make sure that we only have to pay off on 5% of the machines. We obviously want to keep our customers happy and fix their system if it fails after a few months. Come up with at least TWO examples for normal distributions (similar to the above) with numbers and the formula (Google Sheets or Excel) that you used.
