Suppose that you are working as part of a team designing a network for XYZ high school. Consider that the school has six departments, Admin, Academic, Human Resource (HR), Finance, IT support and Sports.

1. Analyse the project hardware requirements along with the number of devices and cost. [3 Marks]

2. Justify the approach you would be taking to design the network for the school. [3 Marks]

3. Using the network simulator (such as packet tracer) design the network. [4 Marks]

4. Illustrate the network configuration you have used. [5 Marks]

Karen Cole, 56 year old female, Karen Cole, a school principal at White House High School. Admitted directly from the Dr.’s office to the IMCU after initial complaint for tightness in her chest, denies pain, and slight shortness of breath. Vital signs are BP: 168/92, P: 90, R: 24, T: 98.6. Her husband insisted that she come. She is insisting that she will only stay 12 hours, because she has to be back to school in the morning.

Write a SBAR report.

For each problem students will write out all steps of hypothesis testing including populations, hypotheses, cutoff scores, and all relevant calculations.

A nationwide survey in 1995 revealed that U.S. grade-school children spend an average of µ = 8.4 hours per week doing homework.  The distribution is normal with σ = 3.2.  Last year, a sample of n = 100 grade-school children was given the same survey.  For this sample, the mean number of homework hours was 7.1.   Has there been a significant change in the homework habits of grade-school children?  Test with α = .05.

A researcher estimates the following regression using 1000 observations:

W=-3.13+1.47*EDU

                                                                                                                         (0.93)     (0.07)

Where W is wage, EDU is years of education and the numbers in parentheses are standard errors of the coefficients.

1. Calculate a 95% confidence interval for the coefficient on EDU.

2. A high school graduate is contemplating whether to obtain a 4-year college degree. How much is his/her wage expected to rise?

3. A high school counselor tells a student that college graduates earn a wage $12 per hour higher than high school graduates. Is this statement consistent with the evidence?

Large Sample Proportion Problem. A survey was conducted on high school marijuana use. Of the 2266 high school students surveyed, 970 admitted to smoking marijuana at least once.  A study done 10 years earlier estimated that 45% of the students had tried marijuana. We want to conduct a hypothesis test to see if the true proportion of high school students who tried marijuana is now less than 45%.   Use alpha = .01.
What is the critical value for this test?

In 1994, 52% of parents with children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 374 of 800 parents with children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did in 1994? Use the α = 0.05 significance level.

a) Determine the null and alternative hypotheses for this scenario.

H0: H1: b) Determine the level of significance.

Answer:
c) Check the assumptions for this problem.

d) Determine the test statistic.

Answer:
e) Determine the p-value.

Answer:
f) Interpret the p-value.

g) What decision do we conclude based on this information? Interpret this in the context of the problem.

1. A high school principal is interested in the amount of time her students spend per week working at an after school job. 37 students are randomly selected and their working hours are recorded. The sample had a mean of 12.3 hours and a standard deviation of 11.2 hours. We would like to construct an 80% confidence interval for the population mean hours worked weekly by high school students.
   1. What critical value will you use for an 80% confidence interval? Give the value and specify whether it comes from the standard normal distribution or the t distribution ( or ).

_______________

1. Calculate the margin of error, E. (You must show the setup to receive credit. You may round to three decimal places, if needed.)

E = _______________

2. Construct the 80% confidence interval for the population mean hours worked weekly by high school students. (Round limits to one decimal place.)

A survey of a group of college students was done to find out how students get to school for the school year. 15% of those surveyed were from out of state. Of those that were in-state, 56% used a car as their primary form of transport to school, 13% used a train and 18% used a bus. Of those that were from out of state, 29% used an airplane, 31% used a car, and 12% used the train.

1. What is the probability that a respondent uses the train?

2. What is the probability a randomly chosen respondent is from out of state and uses the bus as his primary transport?

3. What is the probability that a respondent is from in state, takes an airplane or both?

4. If a respondent is chosen and that person uses a car, what is the probability the respondent is from out of state?  

5. Are primary form of transportation to school and in state/out of state statistically independent?

The term “reverse discrimination”. Discussed with the Bakke case where in Mr. Bakke had the qualifications needed to get into medical school in California. However, in an attempt to make up for discrimination in education in the 1960’s and earlier (Bakke took place in the late 60’s), the school kept 16 of its 100 seats open for minority applicants only; the other 84 could be competed for by anyone. Bakke sued the school, and the Court ruled that he was the victim of reverse discrimination.

Re: the case of Steelworkers v. Weber. In that case, the Court didn’t exactly define reverse discrimination. Rather, the Court set forth a set of factors to use to determine whether reverse discrimination had been committed, or if the employer, school, etc. was acting properly to make up for past discrimination.

Read the Court’s list of factors and discuss your thoughts on the Court’s opinion.
