Professor Brown is interested to see if the graduating seniors in her sociology class have higher or lower college GPAs compared to their respective high school GPAs.
Subtracting the high school GPA from the college GPA and to the nearest hundredth, what is the mean of differences?
A social epidemiologist is interested to see if young adults drink more alcohol if they’re in college compared to those not in college. He selects a sample of 1000 young adults (ages 18-23) in Burlington, VT. Five hundred respondents were attending one of three colleges in the area (sample 1), and 500 were not, and had never been, in college (sample 2). He asked the respondents how many alcohol drinks they consumed on a typical Friday evening. The mean number of drinks for sample 1 (college students) is 3.6, and the mean for sample 2 (non-students) is 1.8.
Click on the epidemiologists’ research hypothesis for this test.
A human factors psychologist wants to know if a new computer-generated voice is either easier or harder to comprehend than human speech. To test this, he gathers 30 volunteers and assigns each to one of two groups. Both groups hear a selection being read. One group's selection is read in the computer-generated voice, the other is read by a human. The results of the experiment, the number of words from the selection that were transcribed correctly, are presented below. Is there a difference in comprehensibility?
Computer Voice Group n = 15 mean = 227 variance = 841
Human Voice Group n = 15 mean = 261 variance = 1764
What is the decision for the hypothesis test conducted in 11.31 with alpha = .05.

Premature Infant Case Study
Nutrition Assessment of Preterm Infant
Patient History: A 980-gram female infant was born at 27 weeks gestation and classified as an appropriate for gestational age premature infant on a premature growth chart. Length was 36 cm, and head circumference was 25 cm. Today, the patient is 21 days old or 30 weeks postmenstral age (PMA) Patient had respiratory distress syndrome, which required intubation and surfactant therapy. Patient is now on room air.
Nutrition History: Patient was on parenteral nutrition, but is now on total enteral feedings of human milk from her mother at 160mL/kg.
Anthropometrics
Weight: 1085g
Length: 38cm
Head Circumference: 27 cm
Nutrition Problem
Nutrient intake is inadequate for the premature infant.
Nutrition Interventions
As discussed on team rounds, human milk fortifier will be added to human milk to provide 24kcal/oz milk. At 160mL/kg, the infant will receive 128 kcal/kg and 3g protein/kg. The fortifier will bring the nutrient content up to meet the guidelines for prematurity.
Questions
How did weight, length, and head circumference plot at birth and at 3 weeks or 30 weeks gestation on the Lubchenco growth chart?
What are the kilocalorie and protein goals per kg for this infant?
What milk is recommended for the premature infant?
What would the feed volume be per feed for feeding every 3 hours at 160mL/kg?
Write one PES for this case study.
Calculate energy and protein intake son fortified human milk with powdered bovine fortified at 160mL/kg.
What should be monitored on a weekly basis in this infant before discharge?

Discussion: Relating Strategically to Others
(Note: Please do not attempt to solve if you cannot answer all. Also, do not attempt to solve if you have answered in my last post. I am looking for a completely different answer
In the internationally-bestselling strategy book, Thinking
Strategically: The Competitive Edge in Business, Politics, and
Everyday Life, authors Dixit and Nalebuff teach strategies
from game theory that can help individuals and organizations to
win in competitive relationships. The teach how to
anticipate the response of a rival and how to
beat the rival. This book advocates competition,
and does so appropriately, as sometimes we must compete. Sometimes
we compete against adversaries, or even evil people or
organizations or governments, that must be defeated. However, all
of life is not about competing.
In the readings from Covey, you learned about "Six Paradigms of
Human Interaction," one of which was "Win-Win or No Deal." Covey
considers this the most ideal of the human interactions and gives a
number of reasons why. Clearly, this is a means to cooperate rather
than compete.
Questions:
1) How does Dixit & Nalebuff's approach equate to Covey's
"Win-Lose" paradigm?
2) How do you think most people see the majority of human
interactions, as opportunities to compete or to cooperate?
3) Can Covey's "Win-Win or No Deal" approach be "strategic" in the
ultimate effects it may accrue?
4) How would you compare and contrast the competitive approach of
Dixit and Nalebuff versus the cooperative approach of Covey?
5) Which of the six paradigms of human interaction do you operate
out of most often? Would it help you to expand your repertoire of
positive, effective, strategic interactions?

A case study is on a Saudi Arabia woman who has entrepreneurial aspirations.
Case: Sarah is a 20 y/o from Saudi Arabia and from an Upper-Class background, who has always been filled with ambition, creativity, and fervor! Furthermore, Sarah has wanted to start her own business since she was 12. For years, she has used her artistic abilities to produce a variety of products she hoped she could sell, but none of them felt right... until now. Sarah created a product- a bracelet- she feels in her "gut" is not only "eye-catching," but will be meaningful to all those who wear it, which she hopes will be everyone. [You decide what meaning the bracelet will hold and with what materials the bracelet will be constructed. This will depend on what's available in the allocated country.] Although Sarah is inspired by her vision, she is also daunted thinking about how she will get her bracelets to the marketplace- what avenue she will take. She is fully aware there are many barriers that stands in her way. It's a lot, but Sarah is motivated; she wants this.
SWOT analysis: Analyze the country’s structural opportunities for a woman starting her own business. Factor some (if not all) the following systems/topics into your discussions: human development standing, human rights, and gender equality policies, education, economics, business infrastructure, technology, political stability.
Find out the Opportunity in SWOT analysis:
-Human Development Standing

-Gender Equality Policies

A steam power plant operates with a boiler that is heated from a heat source at 457 °C and produces 450 ton/hr. of steam. The steam leaves the boiler at 425 °C and 4 MPa. The steam reaches a turbine at 375 °C and 3 MPa and leaves it at 50 kPa with 4% liquid water. This mixture is flown into a condenser that rejects the heat into a river at 17 °C. Water leaves the condenser at 50 kPa and 50 °C and pumped by a pump operating at 10 kJ/kg. The water leaves the pump at 4 MPa.
