PRE-REQUISITE(S)

RATIONALE:

Methods  of  Statistical  Inference are the  basis  of  much  decision
making.  A  basic  understanding of the  concepts  and  techniques  of
statistical  inference  is  highly desirable  for  a  practitioner  of
statistics.

SYNOPSIS:

This  unit  provides the students with a firm grounding in the  theory
and  methods  of  statistical inference and  builds  on  the  material
covered   in   the  unit  Distribution  Theory.  Multiple  regression,
parametric and non-parametric applications are covered.

OBJECTIVES:

Upon successful completion of this unit students should be
able to:

1. Determine point and interval estimators for distributional
   parameters and discuss the properties and distributions of
   those estimators;
   
2. Understand the principles of hypothesis testing and power of a
   test;
   
3. Apply the principles of hypothesis testing to a wide range of
   situations including parametric and non-parametric testing;
   
4. Solve for and make inferences about the parameters of a linear
   model.

OTHER REQUIREMENTS:

1    To   obtain   a   pass  in  the  unit,  students   must   perform
     satisfactorily in all aspects of assessment.
2    The  due date for assessments is the date by which a student must
     despatch an assignment to the USQ. The onus is on the student  to
     provide proof of the despatch date, if requested by the Examiner.
3    Students  MUST  retain a copy of all assignments  which  must  by
     produced if an when required by the Examiner.
4    Extensions   for  assignment  submission  may   be   granted   in
     extenuating  circumstances. The decision to grant  or  refuse  an
     extension is made by the Examiner. Students should be aware  that
     an  application  for  an  extension does not  guarantee  that  an
     extension will be granted.
5    Students  apply for extension by either applying at the  time  of
     submitting  an  assignment  or  applying  in  writing  prior   to
     submitting  an  assignment.  All  relevant  documentation  should
     accompany the application.
6    If  assignments are submitted after the due date and no extension
     is  granted,  then  a  penalty up to a  maximum  of  20%  of  the
     assignment mark for each working day late may apply.
7    No  further assignments will be accepted for assessment  purposes
     after  assignments or model solutions have been released,  except
     in extenuating circumstances.
8    In accordance with University policy and Guidelines,
8.1  an  Examiner  may  grant  an extension of  the  due  date  of  an
     assignment in extenuating circumstances;
8.2  no  assignments  will be accepted for assessment  purposes  after
     assignments  or  model  solutions have been  released  except  in
     extenuating circumstances;
8.3  assignments  submitted after the due date without any extenuating
     circumstances  will  attract a penalty of  at  most  20%  of  the
     assignment mark for each working day late;
8.4  students who submit an assignment after the due date and wish  to
     claim   extenuating   circumstances,  must  provide   documentary
     evidence with the assignment explaining the circumstances;
8.5  the   unit  examiner  shall  consider  a  claim  for  extenuating
     circumstances and decide on the outcome;
8.6  the  decision of the Dean shall be final in any dispute that  may
     arise in the implementation of these guidelines.
9    Restricted   Examination:   a  restricted   examination   is   an
     examination   where  only  those  materials  specified   in   the
     examination paper are permitted during the examination.
