Create a stored procedure that can be used to add a student to the school and a section of a course. 1. If the student already exists, then just add him to the section (do not update information like address). 2. The procedure will require the following arguments (see table definition for types): A. Salutation B. First Name C. Last Name D. Street Address (including City) E. ZIP Code F. Phone Number G. Employer Name (if any) H. Course Number I. Section Number 3. The program should error if any constraints are violated (no last name, bad zip, bad course, bad section) 4. It should rollback changes if these or any other errors occur. 5. The dates in the STUDENT and ENROLLMENT tables should be set to the day the procedure is run. 6. Don't forget that each table has 4 extra required fields ( CREATED_BY, CREATED_DATE, MODIFIED_BY, and MODIFIED_DATE). The current user should be in both 'BY's and the day the procedure is run in both 'DATE's. 7. To test the procedure insert yourself into course 120, section 5. 8. If the insert fails (usually due to the ZIP code not being in the ZIPCODE table, then find a legal ZIP code in that table and use it instead of your own or insert you own ZIP into the table and rerun the procedure. 9. The following SQL can be used to verify that you have successfully placed yourself in the course: SELECT S.LAST_NAME [Last Name], s.FIRST_NAME [First Name], e.ENROLL_DATE [Enrolled On] FROM ENROLLMENT e INNER JOIN SECTION c ON c.SECTION_ID = e.SECTION_ID INNER JOIN STUDENT s ON s.STUDENT_ID = e.STUDENT_ID WHERE c.COURSE_NO =120 AND c.SECTION_NO = 5 structure of

Answer the following questions about one-dimensional motion.

  1. Imagine a fox darting around in the woods for several hours. Can the displacement △xof the fox from his initial position ever be larger than the total distance d he traveled? Explain.
  2. What is the difference between acceleration and velocity? Write a paragraph that would make sense to a 5th grader.
  3. Give an example of a situation where an object has an upward velocity, but a downward acceleration.
  4. What is the difference between average and instantaneous velocity? Make up an example involving a trip in a car that demonstrates your point.
  5. If the position of an object is increasing linearly with time (i.e., △x is proportional to t), what can we say about its acceleration? Explain your thinking.
  6. If the position of an object is increasing non-linearly with time (i.e., △x is not proportional to t), what can we say about its velocity? Explain your thinking.

3. Take the mean and standard deviation of data set A calculated in problem 1 and assume that they are population parameters (μ and σ) known for the variable fish length in a population of rainbow trouts in the Coldwater River. Imagine that data set B is a sample obtained from a different population in Red River (Chapter 6 problem!).

a) Conduct a hypothesis test to see if the mean fish length in the Red River population is different from the population in Coldwater River.

b) Conduct a hypothesis test to see if the variance in fish length is different in the Red River population compared to the variance in the Coldwater population.

please explain to me how to do this step by step. thank you!

Among 800 subjects who completed four years of college, 145 of them smoke. At the 0.04 significance level, use the p-value method test to claim that among college graduates, less than one in five smoke.

(a) State the null and alternate hypothesis

(b) Find the value of the test statistic and the p-value

(c) If a=0.04, are the test results significant or insignificant? Explain in words your conclusion

Show your calculations in detail please..

  1. Suppose that a researcher is conducting a study on fast food habits and assumes that 55% of adults prefer hamburger to pizza. He randomly selects 10 adults and ask whether they prefer hamburger to pizza or not. Based on this information, answer the following questions.

a) (20 pts) Define the random variable (in words) and check whether it is a binomial random variable or not and write your conclusion. Explain your answer.

b) (10 pts) What is the probability that at least 8 adults prefer hamburger?

c) (10 pts) What is the probability that as most 3 adults prefer hamburger?

d) (15 pts) What is the expected number of people who prefer hamburger.

e) (15 pts) Calculate the standard deviation of this random variable and interpret it.
