Question 1

A national survey found that 17% Of Australians consume milk with their breakfast. However, in Victoria, a large milk producer believes that more than 17% of Victorians consume milk with their breakfast. To test this idea, a marketing organisation randomly selected 550 Victorians and asked if they consume milk with their breakfast. It was found that 115 did. Using a 0.05 level of significance, test the idea that more than 17% of Victorians consume milk with their breakfast.

 

Question 2

A rental car company promotes cheap, affordable, old cars to backpackers. The company is interested in estimating the average number of days its cars have been rented for over past few years. The company has the records for all its cars, but to use this data would be very expensive.  To make a quick estimate, a random sample of 32 hire cars is selected from the company records. The number of days each car was hired is given below (in days).

2	3	7	5	8	2	1	5
9	6	3	2	5	10	1	2
4	8	4	3	7	5	8	2
5	3	7	4	9	11	4	3

 

Using these data, construct a 95% confidence interval to estimate the average number of days a car is rented out. Assume that the number of days a car is rented is normally distributed in the population. What can you conclude from your calculations?

 

 

Question 3

Using a people-counting device at the entry to a particular department store in Sydney, the average number of shoppers visiting the store during any one-hour period was determined as 448 shoppers with a standard deviation of 21 shoppers.

(a)    What is the probability that a random sample of 49 different one-hour shopping periods will yield a sample mean between 441 and 446 shoppers?

 

(b)   Interpret your answer in words.

 

(c)    If the random sample size increased to 196 what effect will this have on the standard error of the mean?

 

Question 4

The Bureau of Labor Statistics provides compensation information on and services for various positions. As of May 2008, the national average salary for an RN (registered nurse) was $65,130. Suppose the standard deviation is $9385. For a random sample of 100 such nurses find the following:

(a)    The probability that the mean of the sample is less than $62,500.

 

(b)   The probability that the sample mean is between $64,000 and $67,500

 

(c)    The probability that the sample mean is greater than $66,000

(1 mark)

(d)   Explain why the assumption of normality about the distribution of wages was not involved in the solutions parts to a, b, and c.

 

 

Question 5

Sara is a stockbroker and psychic.  She claims that she provides clients with stock market advice which is in good harmony with a client’s “aura” and “karma” and which is attuned to the client’s own personal astrological chart.  Daniela is a bit wary of these claims, but decides to invest with Sara for a trial period of one year.  She purchases five stocks, on Sara’s advice.  At the end of the year Daniela checks to see whether she could on an average depend on Sarah’s psychic abilities for investment decisions.

 

(a)    State the null and alternative hypotheses, in words and in symbols.

 

(b)   The five stocks that Sara recommended to Daniela had returns of +10%, -15%, +5%, +30%, and –5% over the one-year trial period.  (The overall stock market, as measured by the S&P 500, lost 6% over the course of that year.)  Compute the test statistic. Explain the choice of your test statistic. Use α = 0.05. Give the p-value.

 

(c)    Based on your calculations do you think Sara has investing abilities based on her being a psychic?

 

(d)   What would be a Type I error in this scenario?

Practice Analyzing the Textbook Structure of our Vocabulary Textbook*

Now that you have analyzed the textbook structure from in class activities, practice this strategy using the Textbook Structure Analysis Grid.  Analyze the following pages from your class textbook, Supplemental Readings D – Chapter 6: Crime and Justice in the Twentieth-First Century pp. 23-25. Highlight and label the textbook structures. Take a picture and upload the pages:

When you finish, save it under a different name and upload the completed document (find the submit assignment area to the right and follow the prompts), then write a reflection in the comment section. Use your best writing skills and provide thoughtful, detailed answers.  Address the following items:

1. Strategy:  Describe this strategy (specifically, what things did you look at) in detail. This should be at least 3-5 sentences.
2. Outcome: Describe the outcome:  write a paragraph in which you thoughtfully respond the the following questions:

• How well did the strategy work in your class?
• Did you have to adjust the strategy? How? Why?
• What did you get out of this activity?

By the due date, you will need to submit both the filled-in document: Textbook Structure Grid (as a file upload)  and your responses to the reflection portion (as a comment) for completion credit.

Research Project Overview

The Research Project provides students an opportunity to apply what they have learned about crime and criminology during the length of the course. The overall goal of the Research Project is for students to choose a topic from the course text that interests and challenges them, analyze the topic by reviewing credible and evidence-based scholarly resources relative to the problems and challenges that exist, and apply the theories, concepts, and principles covered in the course. It is recommended that students review all of the assignments, requirements, and grading rubrics so that they know exactly what is expected of them throughout the course and for the final Research Project.

In order to successfully complete the Research Project, three formative assignments and a draft will be completed as deliverables throughout the length of the course:

 

• Assignment 1: Topic Selection and Proposal due Week 2
• Assignment 2: Formal Outline due Week 4
• Assignment 3: Annotated Bibliography due Week 6
• Assignment 4, Part 1: Research Project Draft Submission due Week 8
• Assignment 4, Part 2 (optional): Research Project Re-Submission due Week 10

 

All written assignments must follow these formatting requirements:

 

• Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must conform to the APA formatting requirements. Check with your professor for any additional instructions.
• Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.
• Utilize credible and evidence-based sources such as journal and peer-reviewed articles.
• Display accurate spelling, punctuation, and grammar and write in a clear and organized manner.

minimum 75 words/ At least on reference

Targeting an Audience Demographic:  We can discuss the BLOG Topic

 

Select any topic of a blog or digital media communication effort you like, then select a target audience that is appropriate for the topic. Use descriptive statistics to define your audience and its characteristics and explaining why and how your topic and target audience fit. Include information on the age of the audience, and at least two other relevant descriptors, such as region and income or gender and religion.

Public health research has traditionally focused on problems, deficiencies, disease, and contributing factors to public health problems. In recent years, community health assessments have also included community assets or resources. The process of identifying these contributions to the public health of a community is called asset mapping. One strategy for identifying assets is geographic information system (GIS) mapping. Although the asset-mapping approach to community health assessment is appealing for many reasons, not every asset map is successful or yields results that would be relevant to a community health assessment or public health program. It is important to know the benefits and limitations of asset mapping with regard to community health assessment.

For this week’s Discussion, review the media titled Identifying Assets. Consider the use of community assets in Belize. Using this information, and the information you gathered in the Resources, consider the benefits and limitations to using community asset mapping and GIS in community health assessment.

With these thoughts in mind:

 

Post 3-4 pages of an explanation of one benefit and one limitation of using asset mapping in community health assessment. Provide a specific example of when you might use asset mapping and explain why. Then, explain one benefit and one limitation for the use of geographic information systems (GIS) mapping. Provide a specific example of when you might use GIS and explain why.

Use the Resources and current literature to support your response.
