Create a Factorial application that prompts the user for a number and then displays its factorial. The factorial of a number is the product of all the positive integers from 1 to the number. For example, 5! = 5*4*3*2*1. I also need an algorithm and pseudocode in java please

Use SPSS for this Application Exercise:
A pharmaceutical company tested three formulations of a pain relief medicine for migraine headache sufferers. Volunteers were selected and randomly assigned to one of the three drug formulations. The volunteers were instructed to take the drug during their next migraine headache episode and to report their pain on a scale of 1 to 10 (10 being most pain). The data are below. What can be concluded with ? = 0.05?

a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-way ANOVA

b) Compute the appropriate test statistic(s) to make a decision about H₀.
p-value =  ; Decision:  ---Select--- Reject H0 Fail to reject H0

c) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
?² =  ;  ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

At least one of the formulations differ on pain.None of the formulations differ on pain.   

LEE’s Electric Co. in Glassboro installs electrical fixtures at Rowan dormitories. LEE has been very concerned with the amount of time (Weeks) that it takes to complete electric wiring jobs. Some of her workers are very unreliable. A list of activities and their possible time is given in the following table (a: optimistic time; m: most likely time; b: pessimistic time)

            Activity                       a          m         b          predecessor(s)

Please solve the hypothesis testing problems (#1, and 2) using Minitab as the tool. For each problem, (1) specify the business and statistical hypotheses, (2) specify what the Type I and Type II errors are in this business context, and, the implications of making those errors, (3) include the results from Minitab, (4) draw appropriate conclusions to your statistical hypotheses based on the results, and, finally, (5) present the business conclusions in a short non-statistical summary.

After receiving your bachelor’s degree in personnel management, you were hired by a small but expanding life insurance company. Your first assignment is to develop a more efficient technique for the preliminary screening of applicants for sales positions. Since the firm employs only college graduates, you decide to work with information focusing on their performance during college. A random sample of 25 from the firm’s current sales force is selected and the following information is obtained: Last year’s performance evaluation score College grade point average (GPA) Percent of total college expenses earned by the individual Number of social organizations the individual belonged to

(Source: Unknown – 270RL?)

On the basis of the data obtained, what recommendations can you make regarding the preliminary screening of applicants for sales positions?

1. Sketch and name the parts of manipulator? Give some example of robot End effector:

2. What are the basic components of a robotic system? Explain the functions of each of the components with a neat sketch.

3. What is kinematics? What is meant by pitch, yaw and roll?

4. Frame {2} is rotated with respect to frame {1} about the x - axis by an angle of 600. the position of the origin of frame {2} as seen from frame {1} is 1D2 = [ 9.0 7.0 9.0] T. Obtain the transformation matric 1T2, which describes frame {2} relative to frame {1}. Also, find the description of point P in frame {1} if 2P = [ 4.0 6.0 8.0] T .
