For this assignment, you will be
pretending
g that you are a training supervisor in a hospital. As the
supervisor, you have
to educate your staff on any medical topic that needs to be
explained. Examples:
Confidentiality, OSHA, Handwashing Techniques. Then in a power
point presentation,
you will do the
following:
•
Students will construct a power point training seminar on their
topic. Students
will pretend that you are holding a seminar educating staff on your
topic. The
presentation must be interesting and
informative.
•
The Presentation needs to be at least
10 slides. This does not include your
Introduction slide (name, topic, date) and your reference
slide.
•
The slides must include
graphics.
Students will submit their topics and list two scholarly
references in APA format

For problems 1 and 2, the list shows the results of a study on the use of plus/minus grading at North Carolina State University. It shows the percents of graduate and undergraduate students who received grades with pluses and minuses (for example, C+, A-, etc.)
-Of all students who received one or more plus grades, 92% were undergraduates and 8%
were graduates
- -Of all students who received one or more minus grades, 93% were undergraduates and
7% were graduates
Find the probability that a student is an undergraduate student, given that the student received a plus grade.
Find the probability that a student is a graduate student, given that the student received a minus grade.

You are given a directed graph G(V,E) with n vertices and m edges. Let S be the subset of vertices in G that are able to reach some cycle in G. Design an O(n + m) time algorithm to compute the set S. You can assume that G is given to you in the adjacency-list representation.

For the sentences in (1):
Identify each V:
o Give its subcategorization frame (based on the sentence it appears in).
o List the thematic roles it assigns.
For example:
Ex. John hit Bill in the mouth
hit - V [ ___ NP ] (Agent, Theme)
[NP John ] – Agent, [NP Bill ] – Theme, [NP the mouth ] – Goal
(Theta-roles are discussed in the textbook in the semantics chapter, on pages 158-161.)

a. The torpedo sank the boat
b. The captain sank the boat with a torpedo
c. A brick fell from the sky onto Fred’s big toe
d. Bill heard that John joined the army from Mary

1. The registrar intends to take a probability sample of n = 200 students and project the results from the sample to the entire population of full-time students.
A. If the frame available from the registrars files is an alphabetical listing of the names of all N=4,000 registered full-time students, what type of sample could you take? Discuss
B. What is the advantage of selecting a simple ranadom sample in (1)? why
C. What is the advantage of selecting a systematic sample in (1)? why
D. If the frame available from the registrars files is a list of the names of all N =4,000 registered full-time students compiled from eight separate alphabetical lists, based on the gender and class designation breakdowns shown in the class designation table, what type of sample should you take? Discuss
E. Suppose that each of the N= 4,000 registered full-time students lived in one of the 10 campus dormitories. Each dormitory accomodates 400 students. Is it college policy to fully integrate students by gender and class designation in each dormitory. If the registrar is able to compile a listing of all students by dormitory, explain how you could take a cluster sample.

3. A teacher believes that a new method will improve students’ reading ability. For 8 weeks, she teaches a class of 21 students using these new methods. Meanwhile a colleague uses “traditional” methods to teach his 23 students. At the end of the 8 weeks, all the students are given the Degree of Reading Power Test. Here are the scores:

Are we justified in using the t procedures? Explain.
Give a significance test to check the teacher’s theory. Include all relevant components. (you may wish to list some “background” items first)
Give a 99% confidence interval for the mean difference between the two groups of students
Draw an overall conclusion based on parts B and C.
