Consider the following scenario:After Clark Maxwell met with a lawyer to discuss

Consider the following scenario:After Clark Maxwell met with a lawyer to discuss closing his furniture business and declaring bankruptcy, he wondered how things got to where they were. He knew that his two main struggles had been with employees and products. It seemed that he either had too many employees at a given time to afford the weekly payroll or he had to pay a premium for using day laborers and temp workers to make up for labor shortages. As far as product was concerned, he often had too much of one product that he had to discount to get rid of or he did not have enough of another product to meet the demand. He wished that he could have the success of his cousin, Cait, who never seemed to have these problems with the flooring store she owned. They were in similar industries, he thought, so what was her secret to success?The secret to Cait’s business (in comparison to Clark’s, at least) had to do with the way she applied descriptive statistics to her business. By reviewing her data, she was able to determine how many full- and part-time employees she would need, as well as how that changed depending on different variables in her community. She also made efforts to gather information on consumer’s tastes and preferences in order to have the more valuable (and profitable) carpet in stock and ready to sell.In this Assignment, you will consider basic concepts of descriptive statistics and how they can be used in business.To prepare for this Assignment:Submit your responses to the following prompts.12345678910823837858791812814832862833826752764754774771745736816792793

Part of your task as a scholar-practitioner is to act as a critical consumer of research and ask informed questions of published material. Sometimes, claims are made that do not match the results of the analysis. Unfortunately, this is why statistics is sometimes unfairly associated with telling lies. These misalignments might not be solely attributable to statistical nonsense, but also “user error.” One of the greatest areas of user error is within the practice of hypothesis testing and interpreting statistical significance. As you continue to consume research, be sure and read everything with a critical eye and call out statements that do not match the results.For this Assignment, you will examine statistical significance and meaningfulness based on sample statements.To prepare for this Assignment:For this Assignment:Critically evaluate the two scenarios you selected based upon the following points:Use proper APA format and citations, and referencing.

Answer questions #1-3. Show Work. 1. A basketball player makes a shot

Answer questions #1-3. Show Work. 1. A basketball player makes a shot 72.1% of the time (0.721 as a decimal). Study the player’s next three shots by doing the following:a. Draw a tree diagram and label all of the probabilities on the tree. b. Find and label the probability for each branch of the tree diagram. c. Build a probability model showing the probability of the player making 0, 1, 2, or 3 shots. 2. A bucket contains 4 red balls and 5 orange balls. Two balls are pulled from the bucket, one after another, without replacement. Build a tree diagram showing the different possible outcomes for the two marbles being drawn. Be sure each branch is labeled with its individual probability and include the probability at the end of each branch. 3. Consider that 45% of Americans own a dog, 25% of Americans own a cat, and 40% of Americans own neither. Draw a Venn Diagram for this situation. Be sure to label every region of the Venn Diagram with a word AND the percentage of Americans that fall in each category.

1. What is the null hypothesis for comparing performance ratings by gender?2. Run a t-test on the data in the spreadsheet. Use a two-tailed, two sample equal variance test. What is the t-value? Round to three decimal points (e.g. 0.351)3. Is there a significant difference in performance ratings by gender?a. Yes b. No4. What is the null hypothesis for determining if there is a relationship between Job Level and Performance Ratings?5. Run an analysis to determine if there is a correlation between Job Level and Performance Rating. What is the correlation co-efficient? Round to two decimal points (e.g. 0.04)6. What is the t-value for this relationship? Round to two decimal points (e.g. 0.04)To answer this question, you have to covert the correlation co-efficient to a t value, using the following formula: r= the correlation co-efficientn= the number of observations7. Is the relationship between Job Level and Performance Ratings significant?To answer this question, you can convert the t-value to a p-value in excel using the following command.=t.dist.2t(t, degrees of freedom)t.dist.2t is the command in excel for a two-tailed Student’s T outputThe t in the parenthesis is the value you calculated above (if this is negative, covert it to a positive number by multiplying it by -1)The degrees of freedom = (number of observations – 2)If the value you find is less than 0.05, then the relationship is significant.a. no b. yes

Over the past decade, cases of substance related disorders have appeared more

Over the past decade, cases of substance related disorders have appeared more prevalent in society. From the mental health perspective, research has shown an increase in cases of substance related disorders, particularly with adolescents. This increase has prompted further investigation into adolescent risk and resilience factors, as well as accuracy in diagnosis and appropriate treatment plans. Yet, in cases of adolescent substance use, further investigation is still needed concerning notification rights of parents, legal authorities, and/or case workers. For this Application, review the client case study in the Learning Resources. Consider the characteristics of the client. Which specific characteristics might you consider important in developing a diagnosis? Consider your rationale for assigning particular diagnoses on the basis of the DSM. Also, think about what other information or people you may need to include in the assessment in order to make an accurate diagnosis.The Assignment (3–4 pages)Support your Application Assignment with specific references to all resources as well as current literature used in its preparation. You are to provide a reference list for all resources, including those in the Learning Resources for this course.
