Academic drops have been a concern for university administration due to the negative impact they have on graduation rates and consequently the image of the university.

The Management Department has collected the data for 10 semesters with the following results:

Academic drops from the last 20 to 10 semesters have been:

10, 7, 8, 9, 8, 6, 10, 12, 8, 10.

Has the Management Department seen a significant change in the number of academic drops over the last 5 years?

              b.    The 10 most recent semesters of sample data are: 5, 6, 8, 4, 2, 4, 3, 4, 3, 2.

              c.    Based on your evaluation of these data should the Management Department change their program to lower academic drops?

Deflation refers to the phenomenon of a negative inflation rate. (In 2004, the inflation rate was negative in Hong Kong and we say Hong Kong suffered deflation in 2004.) Many people regard deflation as bad. Can you explain why? Is deflation sometimes good (at least for some people)? (400 words)

A company paid for a 12-month insurance policy on February 1, 2004 for $3,600 and debited the Prepaid Insurance account for the cost of the policy. Assuming no previous adjusting entries have been made, what adjusting entry should be made at March 31, 2004 for the interim financial statements to be properly stated?

1) Discuss the purpose of academic standards? How do teachers use them to plan for instruction? What are your personal thoughts on how standards are used to plan and assess student learning?

2) What are some of the key benefits of using academic standards for planning? What are some of the arguments that critics have to say about academic standards? Explain using evidence from the text.

The schema for the Academics database is as follows. Understanding this schema is necessary to answer the questions in Part B.

DEPARTMENT(deptnum, descrip, instname, deptname, state, postcode) 
ACADEMIC(acnum, deptnum*, famname, givename, initials, title) 
PAPER(panum, title) 
AUTHOR(panum*, acnum*) 
FIELD(fieldnum, id, title) 
INTEREST(fieldnum*, acnum*, descrip) 

The semantics of most attributes are self-explanatory. For each relation, the primary key is underlined and any foreign keys are denoted by an asterisk (*). Some additional information for relations is given below:

• DEPARTMENT: Each academic department (deptnum) belongs to an institution (instname).  
• ACADEMIC: Each academic (acnum) belongs to one department (deptnum).  

• AUTHOR: A paper (panum) may be written by more than one academic (acnum).  
• FIELD: The relation describes research areas, where id is a classification code like B.1.1.  
• INTEREST: The relation describes that an academic may have research interests in several fields (fieldnum), and provide description (descrip) of his/her research.

Find the solution to the heat equation in 3 dimensions on the half space z>0, with homogeneous Neumann boundary conditions at z=0.

u'' + sinu = sinx (-1<x<1)

u(-1)=1, u'(1)=0

solve this boundary value problem.
