Testing for Correlation and Bivariate Regression
Assignment 1: Testing for Correlation and Bivariate RegressionYou had the chance earlier in the week to practice with the correlation and simple linear regression and obtain peer feedback. Hopefully you are excited about the potential these tests hold; equally important is that you recognize some of their weaknesses. Now, it is once again time to put all of that good brainstorming to use and answer a social research question with the correlation and simple linear regression. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure that your variables are metric level variables that can easily be interpreted in these tests.For this Assignment, you will examine correlation and bivariate regression testing.To prepare for this Assignment:Review this week’s Learning Resources and media program related to regression and correlation.Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.Based on the dataset you chose, construct a research question that can be answered with a Pearson correlation and bivariate regression.Once you perform your correlation and bivariate regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.For this Assignment:Write a 2- to 3-paragraph analysis of your correlation and bivariate regression results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.Use proper APA format, citations, and referencing for your analysis, research question, and display of output.

MC Discrete Probability Distribution Expected Value & Development Analysts Worksheet
EXPERIENCE 4 ASSIGNMENT Creating a discrete probability distribution: A venture capitalist, willing to invest $1,000,000, has three investments to choose from. The first investment, a social media company, has a 20% chance of returning $7,000,000 profit, a 30% chance of returning no profit, and a 50% chance of losing the million dollars. The second company, an advertising firm has a 10% chance of returning $3,000,000 profit, a 60% chance of returning a $2,000,000 profit, and a 30% chance of losing the million dollars. The third company, a chemical company has a 40% chance of returning $3,000,000 profit, a 50% chance of no profit, and a 10% chance of losing the million dollars. a. Construct a Probability Distribution for each investment. This should be 3 separate tables (See the instructors video for how this is done) In your table the X column is the net amount of profit/loss for the venture capitalist and the P(X) column uses the decimal form of the likelihoods given above. b. Find the expected value for each investment. c. Which investment has the highest expected return? d. Which is the safest investment and why? e. Which is the riskiest investment and why? When you are finished with your Assignment, upload the completed file below. You can create a spreadsheet with all of the above and submit it or create a document or write it up by hand and scan it.Suppose you work for a company that manufactures electronics. The development analysts estimate that 1% of their flagship product will fail within 2 years of the purchase date, with a replacement cost of $ 1500. A newly hired associate at the company proposes to charge $ 6 for a 2-year warranty. a. Compute the expected value of this proposal. Let X be the amount profited or lost (by the company) on the warranties and P(X) is the probability. E=E= b. Interpret the expected value in complete sentences. (See Example 4.3 in the textbook for an example of this) c. Write your review of the proposal and address it to VP of marketing and promotions. Include the following in your essay: Would the proposal benefit the company? Why or why not? Include the new proposed cost, new expected value, interpretation of the new expected value, and explanation of how the new cost was chosen. Question 1Choose FileNo file chosen PRACTICE E4 A group of people were asked if they had run a red light in the last year. 458 responded "yes", and 423 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year. Give your answer as a fraction or decimal to 4 decimal places A random variable is defined as a process or variable with a numerical outcome. Which of the following are random variables?For families with 5 children, let XX be the number of children with Genetic Condition B. Can the following table be a probability distribution for the random variable XX?Assume that 12 jurors are randomly selected from a population in which 80% of the people are Mexican-Americans. Refer to the probability distribution table below and find the indicated probabilities. The amount of rain, in inches, that will fall next Friday in Dallas, TX.

Round your answer to four decimal places. P(x=6)=P(x=6)= Find the probability of 6 or fewer Mexican-Americans among 12 jurors. Round your answer to four decimal places.
