STAFFING:

PRE-REQUISITE(S)

64621

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 64621 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    It is the student's responsibility to actively participate in all
     classes scheduled for them, and to study all material provided to
     them  or required to be accessed by them to maximize their chance
     of meeting the objectives of the unit and to be informed of unit-
     related activities and administration.
2    To satisfactorily complete the assignments in this unit, students
     must obtain at least half of the total marks available.
3    To be certain of obtaining a passing grade in this unit, students
     must gain at least 50% of the total marks available and obtain at
     least 50% of the available marks in the examination.
4    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.
5    Students   must  retain  a  copy  of  each  item  submitted   for
     assessment.   This must be produced within five days if  required
     by the Examiner.
6    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.
7    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.
8    Assignments  submitted after the due date  without  an  extension
     approved  by the Examiner, may be penalised 10% for each  working
     day late.
9    No  further assignments will be accepted for assessment  purposes
     after  assignments or model solutions have been released,  except
     in extenuating circumstances.
10   In  accordance  with  University's  Assignment  Extension  Policy
     (Regulation 5.6.1), the Examiner of a unit may grant an extension
     of  the  due  date of an assignment in extenuating circumstances.
     This  policy  may  be  found in the USQ  Handbook,  the  Distance
     Education  Student Guide and the Faculty of Sciences' Orientation
     Handbook for new on-campus students. All students are advised  to
     study and follow the guidelines associated with this policy.
11   Restricted   Examination:   a  restricted   examination   is   an
     examination   where  only  those  materials  specified   in   the
     examination paper are permitted during the examination.
11.1 The  only  materials that candidates may use  in  the  restricted
     examination  for  this  unit are calculators  which  cannot  hold
     textual  information (students must indicate on their examination
     paper the make and model of any calculator(s) they use during the
     examination).
11.2 Candidates  may  take  an appropriate non-electronic  translation
     dictionary into the examination.  This will be subject to perusal
     and   may  be  removed  from  the  candidate's  possession  until
     appropriate disciplinary action is completed if found to  contain
     material that could give the candidate an unfair advantage.
11.3 A  list  of the materials candidates may access in the restricted
     examination will be on the frontispiece of the examination paper.
12   Students  who  obtain an overall passing mark,  but  who  do  not
     perform satisfactorily in the examination, may, at the discretion
     of the Examiner, be granted a supplementary examination.
12.1 Students  will  be granted a deferred examination  only  if  they
     perform satisfactorily in the assignments.
12.2 Any supplementary or deferred examinations for this unit will  be
     held in the examination period for semester 2, 2002.
