2. In Pennsylvania, students take the Algebra 1 Keystone exams. If a student scores a 1500 the student earns a Proficient Rating. One teacher claims that his students score above Proficient. In a random sample of 80 students, the mean score was 1505with a standard deviation of 25.578.
a. Is there convincing evidence at the ?=0.05level that his students score above Proficient?(show all four steps)
b. Construct a 90% confidence interval for the meancompletion time of all students who took the exam.(show the math and make the conclusion)
c. How many students would have to be sampled to report a margin of error of 5 points?

In a secondary school, there are 400 male students and 600 female students. 50% of the male students and 55% of the female students are in senior secondary curriculum, the others are in junior secondary curriculum. The school had appointed 8% of senior male students and 10% of senior female students to be the student leaders. No junior secondary student can be student leader.
(a) If a student is selected at random in the school, find the probability that
(i) the student is a senior student.
(ii) the student is a female student leader.
(b) Suppose a student is selected and known to be NOT a student leader, what is the probability that
(i) the student is a male student.
(ii) the student is a senior female student.

Starting at 9 a.m., students arrive to class according to a Poisson process with
parameter λ = 2 (units are minutes). Class begins at 9:15 a.m. There are 30
students.
(a) What is the expectation and variance of the number of students in class by
9:15 a.m.?
(b) Find the probability there will be at least 10 students in class by 9:05 a.m.
(c) Find the probability that the last student who arrives is late.
(d) Suppose exactly six students are late. Find the probability that exactly 15
students arrived by 9:10 a.m.
(e) What is the expected time of arrival of the seventh student who gets
to class?

Is there a difference between community college statistics students and university statistics students in what technology they use on their homework? Of the randomly selected community college students 67 used a computer, 86 used a calculator with built in statistics functions, and 22 used a table from the textbook. Of the randomly selected university students 40 used a computer, 88 used a calculator with built in statistics functions, and 39 used a table from the textbook. Conduct the appropriate hypothesis test using an αα = 0.01 level of significance.

Theories of Management
Answer the following Questions based on our lecture and review on
the different theories of Management. 1. Identify a poor decision
that you have recently made because of poor data gathering? This
can be an experience in the school, work or in your community?
(minimum of 150 words) 2. Describe the 2 best decisions you've made
in your life and identify 5 factors which assisted you in arriving
to that wise decision? (minimum of 200 words) 3. What made you
decide to become a nurse? (minimum of 100 words) 4. What is your
predominant leadership style (a) authoritarian, (b) democratic or
(c) laissez-faire. Defend your answer (minimum of 150 words) 5.
Interview via phone call/messenger a Nurse leader (Charge Nurse,
Head Nurse, CI, etc) Ask them what they perceive to be the top 5
leadership challenges encountered by them today.
C.)Power in Nursing Leadership and Management
-Learning Exercise: Give your opinion and a supporting statement
from a reliable source for the following questions: 1. Research
studies suggest differences in how men and women view power and how
others view men and women in positions of authority. Do you think
that there are gender differences on how people viewed as being
powerful? 2. Who did you feel was most powerful in your family
while growing up and what leadership style does that person uses?
3. Do you think that cultural diversity might be a challenge when
empowering nurses? Think of ways that various cultures may view
power and empowerment differently? 4. List down 1 person you have
encountered in your life who possesses the qualities found in the
various levels of leadership. (Juan Dela Cruz-Uncle- I placed him
under level 1 (Position Level) because...)
