p1hat-p2hat=0.51-0.12=0.39
Standard error = sqrt(0.51*0.49/257+0.12*0.88/155) = 0.041
Margin of error =1.96*0.041 =0.08036 =0.080
Lower limit = 0.390-0.080=0.310
Upper limit = 0.390+0.080=0.470

Seattle University T Distribution Function Statistic Worksheet
1. Use the appropriate t-distribution function to answer the following questions. In your answer, please note the function used and the arguments along with the answer (e.g. using T.INV.2T(0.05, 16) = 2.12.a. 99% of the values in a t distribution with 18 degrees of freedom will be less than or equal to ______.b. 1% of the values in a t distribution with 10 degrees of freedom will be greater than _____.c. 95% of the values in a t distribution with 14 degrees of freedom will be in the interval -_____ to +_____ around the center of the distribution.d. In a t distribution with 10 degrees of freedom, the probability that t is less than 1.5 is _____%.e. In a t distribution with 25 degrees of freedom, the probability that t is greater than 2 is _____%.2. Consider the variable "number living together."a. What is the mean number of people living together off-campus?b. What is the median number of people living together?c. What is the standard deviation of the number of people living together?d. Create a 95% confidence interval for the average number of people living together.e. Fully interpret the interval: what exactly does it tell you? 3. This question concerns the variable “individual rent,” which represents the individual’s share of the rent paid for off-campus housing. Note that many survey respondents did not report their individual rent. a. How many students in the survey reported the rent that they pay individually?b. What are the minimum and maximum individual rents paid by students in the sample?c. What is the average individual rent?d. What is the standard deviation of the rent? e. What percentage of survey respondents left this question blank? Is the fact that some students chose not to answer the question likely to bias the mean upward, downward, or not in any particular direction? Explain your answer. 4. This question asks you to consider the average cost of living off-campus.a. Build a 95% confidence interval for the mean rent paid individually by off-campus students.b. Use your answer to estimate how much a student living off-campus should budget each year for rent. Explain your answer.

MATH 225N Chamberlain College of Nursing Week 4 Probability Discussion
Probability plays a major role in the medical community. Diagnoses are based on probabilities. They are really questions or "what if's", and are answered by the probability that the treatment will be the best for the ailment.
Let's look at probability in terms of both the real world and the medical community.
Survey 30 people to find out if they are left-handed or right-handed, and use the following chart to create a contingency table with the information.
Left handed Right handed Total Female Male Total
Answer the following questions about the information in your contingency table:
If a person is randomly selected from the survey participants, what is the probability that the person will be left-handed?
If you randomly choose a female from the people you surveyed, what is the probability that she is left-handed?
What is the odds ratio of choosing a left-handed female?
What is the relative risk of choosing a left-handed female?
Example
Green
Blue
Total
Cats
40 (A)
20 (B)
60 (A+B)
Dogs
30 (C)
40 (D)
70 (C+D)
Total
70 (A+C)
60 (B+D)
130 (A+B+C+D)
Probability of Green - (A+C)/(A+B+C+D): 70/130 = 0.54
Probability of Green Cat - A/(A+B): 40/60 = 0.67
Odds Ratio of Green Cat - (A/B)/(C/D) or AD/BC: (4040)/(2030) = 1600/600 = 2.67
Relative Risk of Green Cat - [A/(A+C)]/[B/(B+D)]: (40/70)/(20/60) = 1.71
Skim through at least one of the following articles on left-handed vs. right-handed people from the Chamberlain Library. Answer the following question: How do the probabilities and percentages for your study compare to those in the study you read?

AIU Influence of Corporate Social Responsibility on Teton Grand Performance Paper
Two Assignments:
Discussion
Design a training that must be in a video format of you either teaching the concept, or a narrated
presentation of one statistics concept for the course. This is not a training that should focus only on
how to run the analysis but should include "wisdom" on how Teton Grand can use these analyses
moving forward. You are able to do a training on correlations, ANOVA or the opposite t-test (if you did
independent, then you are allowed to show a repeated samples). You cannot rerun any analysis on
variables that we previously ran as a part of this course and calculating descriptive statistics or
zscores is not permitted for this assignment.
This training should incorporate an example of a firm that has used the analysis you are discussing
to their benefit. This means you will need to research a case study and weave it into the deliverable.
The assignment must also include one example of statistics being used to generate business insights
or make business decisions from outside of the Teton Grand case. You will need to research this on
your own. Some good resources are the WSJ and Harvard Business Review. The example must be
related to the statistical concept of your training. For example, you may weave in an example about
how General Motors uses correlations to understand employee satisfaction. The information you find
must be referenced.
Note: If doing a video, it should be approximately 15-minutes in length. A regular presentation
(unless posted as a link, it will still be converted to video using the instructions below) should contain
approximately 15 slides. Your submission should adhere to the APA format and guidelines (i.e. citing
sources appropriately, including references and using APA formatted tables to show data).
Proposal
Review the materials for the week including Geva (2008)
(https://adler.instructure.com/courses/12203/pages/geva-2008) and find two scholarly research articles
on corporate social responsibility then develop a proposal which focuses on at least three key issues
or action items that you would target at Teton Grand as an Industrial and Organizational psychologist
hired to help them think through potential changes to their course curriculum.
Be sure to include the following:
Statistics you have run throughout the course to build a case for options they may want to
consider
A description of the ways in which your proposal addresses social responsibility and corporate
citizenship
Note: Your paper should be approximately 5 pages in length and adhere to the APA format
guidelines (i.e. citing sources appropriately, including references and using APA formatted tables to
show data).
