2. Explain the economic philosophy of the Physiocratic school of thought. What did they consider to be the ultimate source of all wealth? Which classes did they think were productive, which ones did they consider unproductive? Why? What were their thoughts on monarchy and democracy? Why did they advocate a single tax on rent? Why? Explain briefly.

The Garden school want to build a system to calculate students' grade and check they can apply for a scholarship. The system can let the administrator can log in this system (no database required) to work with different students' marks. You need to use the weight of each unit to calculate the final grade. The administrator should enter their account and password at first. They can start work when the account and password are correct. The administrator needs to typing students ID, and according to your prompts to type the following units' marks. The system must according to those marks to provide the final grade of the students. According to the description, the system should analysis each unit's marks to provide suitable prompts to let the administrator know that the student meets requirements. According to those results, the administrator can inform those students. Unit Name Description Weight Math Students can attend maths contest when they get 90 marks 30% Biology Students can apply the unit Ecology when they get 75 20% IT Students can get a Microsoft certificate when they get 85 in this unit 20% Painting Students' productions can be displayed on the school website when they can get 85 in this unit. 10% History 20% Final The student has the opportunity to apply for a scholarship when the final grade is HD. 100% Grade table Marks Grade Note >= 85 HD >=75 D >=65 C >=50 P <50 F Students need to enrol this unit next semester. Units' marks are 0 Not attend Students need to explain their absence and enrol this unit next semester. In the system, staff can type student’s id to find the students mark details, and staff can get a .txt file of the student's mark details. In the system, the student can use an account and password to login the system to check their marks and enrol their units. Students can type in the unit code to enrol their unit. One student can enrol no more than 4 unit at a semester. If a student enrols the unit first time, the fee of the unit will be plan A. If the student is the second time to enrol this unit (due to failed last semester), the fee of the unit would be plan B. For example, a student got F in math last semester; the student needs to enrol the unit this semester, but the fee is 1200 instead of 1000. The following are the units that students can enrol Unit Code Unit Name Fee (plan A) $AUD Fee (plan B) $AUD 4483 Math 1000 1200 4485 Biology 1580 1780 4486 Information technology 1580 1780 4487 Painting 1580 1780 4488 History 1000 1200 4489 Ecology 1000 1200 8873 Accounting 1000 1200 8872 Chief 1580 1780 8871 Spanish 1200 1200 Student can get a .txt file when they finish their enroll. There is a student record which is already saved in your program, the student can login the system to check his unit marks and final grade. The student will get Plan B fee when he enrols failed units. You need to display the fee of each unit, and the total fee of all unit. Staff also can get the student information when type in the student ID: Name: Tom ID: u123 Password: u123 Math: 48 Biology: 52 IT: 53 Painting: 45 History: 38 Final grade: F The student needs to enrol math, painting, history next semester.

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.5 years with a standard deviation of 0.9 years.

Step 1 of 2:

If a sampling distribution is created using samples of the ages at which 45 children begin reading, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.

Tracy is in her last semester of nursing school where she is taking a course in which her class learns about the importance of evidence-based practice. Dr. Minturn, the nursing professor who teaches the course, has asked the students to write a paper about a mock research study of their choosing. The students are to pose a clinical question and then map how they would create a research study around the question. They are not to actually carry out the research, but they are to envision what their study would look like and then map it on paper.

1. Tracy needs to conduct a literature review of her chosen phenomena of study. One database she can use to obtain peer reviewed nursing articles is:

Suppose that a principal of a local high school tracks the number of minutes his students spend texting on a given school day. He finds that the distribution of minutes spent texting is roughly normal with a mean of 60 and a standard deviation of 20. Use this information to answer the following questions.

1. Based on the statistics, what is the probability of selecting at random a student who spends an extreme amount of time texting – either less than 10 minutes OR more than 110 minutes?

2. Based on the statistics, what is the probability of selecting at random (with replacement) two students who spent a below-average amount of time texting?

3. Based on the statistics, what is the probability of selecting at random (with replacement) two students who spent more than 75 minutes texting?

4. Based on the statistics, what is the percentile rank of a student who spent 100 minutes texting?

5. Based on the statistics, find the two numbers of minutes that define the middle 95% of students in the distribution. What is the value for the lower number that you found?

6. Based on the statistics, find the two numbers of minutes that define the middle 95% of students in the distribution. What is the value for the higher number that you found?

You are looking to take out a ​$47，000 loan to pay for school. The loan would be a​ five-year loan. The lender offers you a 7​% interest rate on the loan and also offers to structure it in one of three​ ways:

what‘s your ending balance of the first year?
​a) As a discount loan
​b) As an​ interest-only loan

c) As an amortized loan.

A sample of 14 children in the 5th grade of North Stratfield School run the 100 meter dash in a average time of 26.2 seconds. Assume the bias adjusted sample standard deviation of the individual 100 meter dash times is 9 seconds.
Construct a 99% confidence interval for μμ, the true population mean 100 meter dash time. Since n is small, the t statistic will be used in deriving this confidence interval.
What is the degrees of freedom parameter that should be used to derive the t-value? ______

What is the confidence interval? Give your answers as decimals, to two places

________ < μμ < ________

There is 540 peoplein attendance at a high school basketball game. The admission prices are $5 for students, $7 for parents, and $10 for faculty. The total revenue for the game is$3000. There are 9 times as many students present as parents. Use the variable names: s = # of students, p = # of parents and f = # of faculty. Find the number of each group in attendance by writing a system of 3 equations in the three variables and solving the system.

The scores of students on the SAT college entrance examinations at a certain high school had a normal distribution with mean μ=544 and standard deviation σ=29.1.

(a) What is the probability that a single student randomly chosen from all those taking the test scores 548 or higher?

For parts (b) through (d), consider a simple random sample (SRS) of 35 students who took the test.

(b) What are the mean and standard deviation of the sample mean score x¯, of 35 students?

(c) What z-score corresponds to the mean score x¯ of 548?

(d) What is the probability that the mean score x¯ of these students is 548 or higher?

1. The average expenditure per student for a certain school year was $10337 with a population standard deviation of $1560. A survey for the next school year of 150 randomly selected students resulted in a sample mean of $10798. At α =0.01 level of significance, can it be concluded that the average expenditure has changed?

2. (10 pts) Suppose when you were visiting universities and deciding which to attend, the admission officers at Tennessee Wesleyan(TW) claimed TW students graduate in 4.25 years or less. You are now a student at TW and notice that a lot of students are graduating in more than 4.25 years. Therefore, you doubt that you were given accurate graduation rates by the TW admission officers. You collect data and compute graduation rates of TW graduates from the last 10 years (n=10). You obtain a mean graduation rate of 4.74 years and a standard deviation of 0.76 years. Do you have strong enough evidence to prove that TW admissions officers are not providing accurate rates at α =0.05 level of significance? Use hypothesis testing to determine your conclusion.
