Students in a representative sample of 65 first-year students selected from a large university in England participated in a study of academic procrastination. Each student in the sample completed the Tuckman Procrastination Scale, which measures procrastination tendencies. Scores on this scale can range from 16 to 64, with scores over 40 indicating higher levels of procrastination. For the 65 first-year students in this study, the mean score on the procrastination scale was 36.9 and the standard deviation was 6.46. (a) Construct a 95% confidence interval estimate of μ, the mean procrastination scale for first-year students at this college. (Round your answers to three decimal places.) , (b) Based on your interval, is 40 a plausible value for the population mean score? Yes No What does this imply about the population of first-year students? This implies that students at this university never have high levels of procrastination. This implies that on average, students at this university do not have high levels of procrastination. This implies that students at this university sometimes have high levels of procrastination. This implies that on average, students at this university do have high levels of procrastination. This implies that students at this university always have high levels of procrastination.

Let's take a moment to make some connections in the material we have been exploring for the last several weeks.

First, examine the decision-making model introduced on page 148 of our textbook. As mentioned in our textbook, this model reflects the "five steps necessary to make an informed and desirable decision" (Sukiennik & Raufman, 2016,p. 148). The first step is to define a goal.

Return to this discussion to share one clearly defined personal goal along with specific objectives to help you achieve it, as illustrated on page 152 of the textbook. As you work on your goal, review the decision-making styles on page 144 of the textbook and discuss if you anticipate any of these to impede your progress.

Are you not sure where to start? Perhaps you want to address a time or stress management challenge identified earlier in the course that you have not yet overcome, or you can work on how you manage your financial resources as discussed on pages 154-157.

To wrap up your discussion post, how is the goal you define for yourself going to help your academic or professional success?

A study was conducted to find out the type of relationship between randomly selected15 Masters of Education Degree students scores in Research Methods and Statistics at Mount Kenya University during the 2012/2013 academic year. The results were as displayed in the table below.

Allisson Russo is a 15 year old girl admitted to the Emergency Room with Right , lower quadrant pain. She is eventually diagnosed with appendicitis and scheduled for an appendectomy. After visiting Allison in the Er, the surgeon Alerts the Operating Room nurse, Ms. Wendy Harnes that the surgery will take place in an hour. Allison is HIV positive from emergency medical acre and blood transfusions that she received six years ago, following an auto accident. Allison does not know that she is positive, at the request of her parents, who are born high-powered attorneys. Allison tells Ms. Harnes that she used to to be involved in sports but has dropped these activities in school because of feeling more tired than usual. She thinks that her academic studies are simply requiring more of her attention , but her mother has suggested that perhaps she would be seeing a new doctor soon. Allison asks the nurse “ Do you think being tired at my age is a serious concern? I thought all teenagers feel like this. I feel that I have a serious health problem.” How should Ms. Hayes respond to Allison?

i. The manufacturing cost of the widgets your company makes has dropped by 50%. One of your customers, Sam, tells you he knows this because he is best friends with your company’s Vice President of production and asks you for a discount on his order. Your boss accepts this request. Your other customer, Sue (who is one of your best friends and knows nothing about the drop in manufacturing costs), places the exact same order for widgets as Sam. Do you offer her a similar discount? Do you tell her about the drop in manufacturing costs?

ii. You are a working student, a manager of a company. Your company has engaged you for a whole month, so you have not had enough time to focus on completing and submitting your assignment. You have 48 hours to submit a 3,000 words assignment. Your classmate has offered to do your assignment for you, but your religious values does not permit you to allow this academic misconduct. What will you do?

Data modeling is a key component to creating a database. There are all different aspects of data modeling, with concerns from various things to the methodology of modeling, to software, to interfaces used between each model.

Paper: Write a 3 page paper (at model 1.2 spacing, 12 pt font, 1 inch margins with at most one half of the paper including a figure, citations not included) on some aspect of data modeling in industry. You must use reliable academic and industry resources. You must have at least one resource that connects your topic to industry. Write up should not exceed 4 pages, excluding citations. Example topics include:

• Data modeling challenges in transportation industry (logistics)
• Data modelling notations or techniques other than the ER or relational model (Bachman diagrams, Barker's notation, Chen's notation, Data Vault Modeling, Extended Backus–Naur form, IDEF1X, Object-relational mapping, Object-Role Modeling, Relational Model, Relational Model/Tasmania)
• Data modelling case study for a specific company.
• Suggestions for other topics from students will also be taken.

We consider a randomized experiment, the Tennessee STAR experiment, where students and teachers are randomly assigned to either a small class (15 students) and a regular class (24 students).

We want to estimate the effect of smaller class in primary school and use the following linear model:
Score = β0 + β1ClassSize + Controls + u,
where Score is student’s academic score, Class Size is dummy for small class, and controls includes free lunch status, race, gender, teacher characteristics and so on.

However, you estimate the following model instead:
Score = α0 + α1ClassSize + v

A. Provide the conditions for the OLS estimator for α1 to be unbiased.
B. Provide the Gauss-Markov assumptions for the OLS estimator for α1.
C. Evaluate the sign and the magnitude of bias α1 if teacher’s experience has positive effect on score and more experienced teachers are more likely to be assigned to regular class.
D. Suppose that teachers and students are randomly assigned to either a small class (15 students) or a regular class. Compare α1 to β1.
E. How does the OLS estimator for β1 change as we additionally include parental characteristics as Controls?
