Provide an example that follows either the binomial or Poisson distribution, and explain why that example follows that particular distribution. In your responses to other students, make up numbers for the example provided by that other student, and ask a related probability question. Then, show the work (or describe the technology steps), and solve that probability example. Solution: For this week's discussion on discrete probability variables, I chose to focus on binomial distribution. To...

Keep your eyes and ears open as you read or listen to the news this week. Find/discover an example of statistics in the news to discuss the following statement that represents one of the objectives of statistics analysis: "Statistics helps us make decisions based on data analysis." Briefly discuss how the news item or article meets this objective. Cite your references. Also, keep in mind and discuss how the impact of your study on your patients or staff might differ if you found it in a journal....

MATH399 Statistics—Lab Week 2 This assignment is worth 50 points.  Please review the grading rubric to determine how points are distributed throughout the assignment.   Name:_______________________   Statistical Concepts: Using Excel Graphics Shapes of distributions Descriptive statistics   NOTE: Directions for all labs are given based on Excel 2013 for Windows.

Suppose you are given data from a survey showing the IQ of each person interviewed and the IQ of his or her mother. That is all the information that you have. Your boss has asked you to put together a report showing the relationship between these two variables. What could you present and why? Solution: Correlation is used to determine whether or not a relationship exists whiles Regression is determining the equation that relates one variable to another. In line with the given information o...

If you were given a large data set (i.e., sales over the last year of our top 100 customers), what might you be able to do with these data? What might be the benefits of describing the data? Solution: If I were given a large data set there are many things that I would be able to do with this data. For example, I could use the mean number and determine the average number of sales that are being made and from there I could use that information to find the variance of the data which is useful...

We rely heavily on statistics and statistical research in the health and helping professions. The outcomes from this work help us identify the best methods for helping and caring for clients and patients. Discuss at least two concepts from the course that you can use in your future career. Be sure to state the concept, how you would use it, and why that approach would be the best approach for the situation. Solution: Studying this course has to a huge extent equipped me with extensive know...

If a regression analysis was to be completed on body mass index (BMI), what could be an independent variable in that analysis? Why? If we could, what other independent variables should be included in the analysis? What statistic(s) would show the value of that regression in understanding BMI? Alternatively, find an article that uses regression analysis to study a medical concern. In that study, what was the dependent variable and what were the independent variable(s)?  Further, how would you ...

Describe a hypothesis test study that would help your work or conclusions in some way. Describe what variable would be tested and what would be your guess of the value of that variable. Then include how the result, if the null were rejected or not, might change your conclusions or actions in some way. Solution: Hypothesis testing is critical owing to the fact that it helps in determining the probability that a given hypothesis is true (Bennett, Briggs, Triola, 2018).  Taking this into acco...

Thinking of the many variables tracked by hospitals and doctors' offices, confidence intervals could be created for many of them. What variable might be most helpful in your work to be able to create an interval that captures the true value of patients with 95% confidence? What would limit the ability to create such an interval? Solution: According to Bennett, Briggs, and Triola (2018), confidence intervals refer to a range of values that are likely to contain the true value of the populat...
