In a study of memory recall, 8 students from a large psychology class were selected at random and given 10 min to memorize a list of 20 nonsense words. Each was asked to list as many of the words as he or she could remember both 1 hour and 24 hours later, as shown in the following table:

Subject 1 2 3 4 5 6 7 8

1 Hour 14 12 18 7 11 9 16 15

24 Hours 10 4 14 6 9 6 12 12

Is there evidence to suggest that the mean number of words recalled after 1 hour exceeds the mean recall after 24 hours by more than 3? Use a level .01 test.

Create a new worksheet and name it as “Roster”. Assume that you are the TA for Mgtop 470. You have the class roster in the worksheet “Roster” and the full names of students are in column A, starting in Cell A3, with last name last and case insensitive (such as Ben ALT). Write a sub that counts the number of names in the list with last name ALT and then displays this count in an MsgBox that is titled “Number of ALTs” and has an Exclamation icon button. Note that there might be last names, such as DALT, which should not be counted.

Overview Diffusion of innovations (DOI) is a framework which has its root in rural health, where more emphasis on marketing is required in introducing new health behaviors or technologies. It is based on five processes: Innovation Development, Dissemination, Adoption, Implementation, and Maintenance. use of DOI in developing physical activity interventions in children and adolescents. plan your own intervention by using lessons learned from these methods. how students view physical education. Make a 5-point list of what you will do

Students at a college randomly selected 217 student cars and found that they had ages with a mean of 7.89 years and a standard deviation of 3.67 years. They also randomly selected 152 faculty cars and found that they had ages with a mean of 5399 years and a standard deviation of 3.65 years.

a) Using a 0.05 significance level, are student cars older than faculty cars?

Students are to research leadership styles to determine a specific leadership style that they would prefer to work for. Be sure to list what qualities make this style of leadership preferable and why you feel that this style would make you effective compared to other styles you discover in your research. The paper should be no more than 2-3 pages. Find at least 2 scholarly sources to support your choice. Be sure to cite materials used to develop your paper and include a reference page.

University students should pay the full cost of their studies because a university education benefits individuals rather than society as a whole. To what extent do you agree or disagree with this opinion?

– Decide where you stand; agree or disagree. State in the thesis statement your stand.

– List out all the reasons on why you chose to agree/disagree ( 2,3 reasons is enough)

– Explain with example or facts all these reason

– Conclusion; restate your stand and summarise all the reason.

One class has 30 students. Ten are women (F) and US citizens (U); 12 are male (M) and US citizens; 6 are women who are not US citizens (N); 2 are men who are not US citizens. A name is selected at random from the class list and it is female. Determine the following probabilities:

1. P (FU)
2. P (FN)
3. P (MU)
4. P (MN)
5. P (F)
6. P (M)
7. P (U)
8. P (N)
9. P (U/F)

Let V = 20x2yz - 10z2 V in free space, (a) Determine the equations of the equipotential surfaces on which V = 0 and 60 V. (b) Assume these are conducting surfaces and find the surface charge density at that point on the V = 60-V surface where x=2 and z= 1. It is known that 0 V 60 V is the field-containing region, (c) Give the unit vector at this point that is normal to the conducting surface and directed toward the V = 0 surface.

Consider the following set of requirements for a university information system that is used to keep track of students’ transcripts.

R1: The university keeps track of each student's name, student number, class, and degree program.

R2. The university consists of various departments. Each department is described by a name, department code and phone.

R3. Each course has a course number, course name, and credits.

R4. Each section has an instructor, course number, and section number. There might be multiple sections of each course offered in the semester.

The other requirements for this application are:

R5: An administrator can update the courses to be taught by instructors, and enter the list of students taking a course.

R6: An instructor can enter and update the grades of the course(s) taught by this instructor.

R7: A student can request a grade report from the information system.

REQUIRED

1. Create A Use Case Diagram
2. Create A Class Diagram

3. Use matlab to plot the output voltage of an inverting operational amplifier given the following conditions: K = Gain of the amplifier = 12.5. Vi = input voltage -2.5 < Vi < 2.5 V], (use 0.25 increments). V+ = positive power supply voltage, V+ = +20 V. V- = negative power supply voltage V- = -20V. Vo = output voltage Vo = -KVi Recall that if the output voltage Vo is greater than V+, or less than V-, the output voltage Vo gets clipped to the V+, or V- voltage, (clipped at the rail voltage).
