Step 2: Do

Run a Regression for the Data File NASCAR (Chapter 15) using the video How to Add Excel’s Data Analysis ToolPak (Links to an external site.) for assistance.

In a managerial report,

Suppose you wanted to predict Winnings ($) using only the number of poles won (Poles), the number of wins (Wins), the number of top five finishes (Top 5), or the number of top ten finishes (Top 10). Which of these four variables provides the best single predictor of winnings?

Develop an estimated regression equation (look at Equation 15.6 in our textbook as an example) that can be used to predict Winnings ($) given the number of poles won (Poles), the number of wins (Wins), the number of top five finishes (Top 5), and the number of top ten (Top 10) finishes. Test for individual significance, and then discuss your findings and conclusions.

Step 3: Discuss:

What did you find in your analysis of the data? Were there any surprising results? What recommendations would you make based on your findings? Include details from your managerial report to support your recommendations.

## Use data from a table to calculate murder rates for five cities in the US.

Using the information from the table above, calculate the murder rates (per 100,000) for each of the five cities (include 2 decimal places in the rates. For example, 50.00).

Copy the table into a Word doc and add a column that is titled Murder Rate (see example above). Then enter the murder rate for each city.

2. What is the lowest murder rate in the table? What is the city that has the lowest murder rate?

3. What is the highest murder rate in the table? What is the city that has the highest murder rate?

4. Were you surprised by these results? Why or why not? Explain your answer.

## Statistics short answer questions

These are short answer questions.

4.) Explain how to generate a simple random sample of 20 employees out of the 85 total

employees who are working at a candy bar factory.

5.) Explain how generating a simple random sample of 20 candy bars off the production line

would be different than generating a simple random sample of 20 employees.

6.) Explain why sampling without replacement is preferable to sampling with replacement

7.) Provide an example of when you might want to take a systematic random sample

instead of a simple random sample, and explain what the advantages of a systematic

random sample might be.

8.) Provide an example of when you might want to take a stratified random sample instead of

a simple random sample, and explain what the advantages of a stratified random sample

might be.

9.) Provide an example of when you might want to take a cluster random sample instead of a

simple random sample, and explain what the advantages of a cluster sample might be.

Also, explain how you would choose the cluster sample.

10.) A telephone survey evaluating unemployment claims asks the question, “Do you think

people should be paid not to work?” The survey was conducted during the hours of 8:00

am to 4:00 pm for homeowners with listed landlines. What are some possible sources of

error that might arise in their effort to estimate the population proportion who would

answer “yes” or “no” to this question? (Be sure to both identify any relevant types of

error with one of your vocabulary words and explain why it might occur.)

11.) Define the concept of “sampling error”. (Note: Your definition should include the idea

of sample, population, statistic, parameter.)

## I need a discussion board writing based off statistics

Thank You.There are three parts to this discussion: Read, identify your selected news article, reply to the questions below.

Prepare: Prior to beginning work on this discussion, read Chapter 5: Statistical Reasoning and Chapter 6: Putting Statistics to Work in your course text.

Research a news article or website that provides data sets and statistical report information such as the United States Census Bureau (Links to an external site.), the U.S. Energy Information Administration (Links to an external site.), the Centers for Disease Control and Prevention’s National Center for Health Statistics (Links to an external site.), or the National Center for Education Statistics (Links to an external site.). Your selected news article or website should provide enough information to allow you to fully answer each of the questions below.

Write: For your post, identify your selected news article or website using correct APA formatting followed by your fully developed answers to each of the following:

Describe the role of statistics in the news article or report.

What was the population of the study?

What was the sample?

Do you believe the statistical results are believable and meaningful?

Use the Eight Guidelines for Evaluating a Statistical Study mentioned in Chapter 5B to explain why the results are believable and meaningful (or why not).

What sorts of statistics (e.g., graphical, non-graphical, hypotheses, correlation, averages, etc.) were used in the report?

How was the data distributed?

How are distribution and variation important in any statistical study?

Was any margin of error mentioned in the report?

If no margin of error was mentioned, then assume that it is 2%. Interpret the margin of error in terms of 95% confidence interval.

Showcase your critical thinking skills and include supporting detail to back up your conclusions.

Your initial post should be at least 250 words in length. It should show all the required math work and explain all the steps. Also include a simple reference for any used resource. For example: Washington Post dated August 13, 2018 or retrieved from .

Your initial discussion thread is due on Day 4 (Friday), and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Carefully review the Grading Rubric for guidance on how your discussion will be evaluated.

Guided Response: Respond to at least three different peers by Day 7. Give specific thoughtful and substantive responses addressing their points and back up your ideas with references. If you notice classmates forgetting to complete part(s) of the discussion, tactfully encourage them to complete the remaining part(s). Be specific. Give a hint, if possible.

Have they answered all the questions pertaining to their problem?

Have they used all the required resources and cited the references correctly?

Do you understand their answers and agree with their conclusions and viewpoints?

What are your arguments against their answers?

Remember, in order to view your peers’ work and respond to their posts you need to submit your completed work, preferably by Day 4. Without your submission, their posts will not be viewable to you.
