In 1997 a woman sued a computer keyboard manufacturer, charging that her repetitive stress injuries were caused by the keyboard (Genessey v. Digital Equipment Corporation). The jury awarded about $3.5 million for pain and suffering, but the court then set aside that award as being unreasonable compensation. In making this determination, the court identified a "normative" group of 27 similar cases and specified a reasonable award as one within 2 standard deviations of the mean of the awards in the 27 cases. The 27 award amounts (in thousands of dollars) are in the table below.
39 60 75 115 135 140 149 150 234 290 340 410 600 750 750 750 1050 1100 1139 1150 1200 1200 1250 1572 1700 1825 2000
What is the maximum possible amount that could be awarded under the "2-standard deviations rule"? (Round all intermediate calculations and the answer to three decimal places.)

You decide to buy 700 shares of stock at a price of $74 and an initial margin of 50 percent. What is the maximum percentage decline in the stock price before you will receive a margin call if the maintenance margin is 35 percent? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places. Input the amount as a positive value.)

Algebra scores in a school district are normally distributed with a mean of 74 and standard deviation 6. A new teaching-and-learning system, intended to increase average scores, is introduced to a random sample of 30 students, and in the first year the average was 76.
(a) What is the probability that an average as high as 76 would have been obtained under the old system?
(b) What is the null hypothesis for testing the new system, and what is the alternative hypothesis?
(c) Is the test significant at the 0.05 level? What about the 0.01 level? Explain your answers.

A large sports supplier has many stores located world wide. A regression model is to be constructed to predict the annual revenue of a particular store based upon the population of the city or town where the store is located, the annual expenditure on promotion for the store and the distance of the store to the center of the city.
Data has been collected on 30 randomly selected stores: show data
a)Find the multiple regression equation using all three explanatory variables. Assume that X1 is population, X2 is annual promotional expenditure and X3 is distance to city center. Give your answers to 3 decimal places.
y^ = + population + promo. expenditure + dist. to city
b)At a level of significance of 0.05, the result of the F test for this model is that the null hypothesis is, is not rejected.
For parts c) and d), using the data, separately calculate the correlations between the response variable and each of the three explanatory variables.
c)The explanatory variable that is most correlated with annual revenue is:
population
promotional expenditure
distance to city
d)The explanatory variable that is least correlated with annual revenue is:
population
promotional expenditure
distance to city
e)The value of R2 for this model, to 2 decimal places, is equal to
f)The value of se for this model, to 3 decimal places, is equal to
g)Construct a new multiple regression model by removing the variable distance to city center. Give your answers to 3 decimal places.
The new regression model equation is:
y^ = + population + promo. expenditure
h)In the new model compared to the previous one, the value of R2 (to 2 decimal places) is:
increased
decreased
unchanged
i)In the new model compared to the previous one, the value of se (to 3 decimal places) is:
increased

for.
Note to Student
This unit of competency will require you to respond or perform a task based on the questions posed on short answers in Part 1 of these assessment, and also for you to read and understand the case studies below before you attempt to respond to the question or perform the task.
Case 1
As IT personnel, you were asked by your line manager to contribute
to the MGIT Intellectual Property and Copyright Policy
Statement.
You will find the copy of the statement below – this particular
statement is incomplete, please think of how the IT department can
protect its intellectual property and to meet its copyright
legislative obligation.
MGIT INTELLECTUAL PROPERTY and COPYRIGHT Policy
Statement_V2.0
Purpose:
The purpose of this policy statement is to communicate the MGIT
Intellectual Property and Copyright Policy Statement regarding the
protection of all training and assessment documentation as well
Information Technology programs that MGIT staff and contractors had
developed on behalf of MGIT.
The policy also clearly instruct all MGIT course developers the
rules when using other author’s work in the development of their
training and assessment resources.
This policy also includes and describes how the developed and
implemented documentation and program will be managed, maintained,
access and stored.
Scope:
Staff
Student
Contractors
Protection of MGIT Intellectual Property:
All training and assessment documentation commission by MGIT is
considered as a property of MGIT. Once the documentation process
has commenced, staff involved in the documentation development will
do the following;
Will carefully save, store and version control the documentation as
per MGIT Document Version control Policy and Procedure.
Once the documentation is finalized, sign off by the approving
departmental manager will be required and the document will be
considered final and has the appropriate version control
The document will disseminated in a PDF format and ready for
use

drive is not permitted at all times.
Reviewing or updating documentation without the approval of
departmental managers is not permitted at all times. Necessary
permission must be sought before attempting any change or
review
Copyright Commitment:
MGIT course or Training and Assessment Developer must adhere to the
Copyright Act of 2006, in order to do so the Training and
Assessment Developer must do the following;
To adhere to the Copyright Act of 2006 provision when providing or
attaching copies of textbook, journals, etc. to be provided to
students or other clients
To provide accurate references by using Harvard Referencing
style
Information Technology Programs:
Any software programs developed on behalf Of MGIT is considered a
property of MGIT. All program specification, scoping and program
documentation must be carefully saved and stored. Access to staff
to the software programs will be pre-determined by IT and HR
Personnel.
Task Case Study 1:
