Testing effect

This effect also exist in this scenario ,As the questions asked in pretest influence the performance of employees adversely.

This is another threat to internal validity which exist in this scenario.


Mortality

Mortality effect of threat to the internal validity exist I this scenario , as some of the employees left organization during program .Which contaminate the program because leaving of some members hinder the training process and make it difficult to intreprete the exact result.

Following threats to internal validity does not exist in the scenario above.


Selection bias effect

This is the threat which exist due to non random selection of subjects for 2 comparison groups.Whereas in scenario above members of 2 groups were selected randomly.So, there was no selection differentiation in scenario.

ECO402 - Assignment No. 2 solution

A.

If we examine the market for rice in Pakistan during the year 2007 and 2009, the demand of rice was higher in the year 2007 but it fell down during the year 2009, due to the drop in the export demand of rice. But the Government wants to keep the price of rice at higher level. The given equations show the quantity demanded and quantity supplied of rice during the year 2007.

Year 2007: Demand: Qd = 1,600 - 125P

Year 2007 Supply: Qs = 440 + 165P

a. Calculate the market clearing price level and quantity in the year

2007, in that year there were no effective limitations on the

production of rice.

...........................................

Market clearing price condition

Quantity demanded = Quantity supplied

1600-125p = 440+165p

1600-440 = 165p+125p

1160 = 290p

P = 1160/290

Now: P = 4

Now putting values in the quantity demanded side or supply side

We are putting values in the quantity demanded side

Qd = 1600-125p

= 1600-125(4)

Qd = 1100

b. Why the government wants to keep the price at higher level i.e. to

$5.50 when there is decline in export demand. Will it effect on the

quantity demanded or quantity supplied equation and curve and how

much?

Yes it has effect on quantity demanded or quantity supplied.

Qd = 16, 00 – 125($5.50)

Qd =16, 00 – 687.5

Qd = 912.5

Quantity demanded is equal to Qd = 912.5

Qs = 440 +165($5.50)

Qs = 440 + 907.5

Qs= 1347.5

Quantity supplied is equal to Qs = 1347.5 Ans

c. Now with the help of new quantity equation calculate what should be

the quantity of rice which the government must buy?

Now

Excess supply = Qd –Qs

= 912 .5 -1345.7

= -435

The government will buy Q = 435

B.

Suppose a profit-maximizing monopolist is producing 800 units of output

and is charging a price of $70 per unit.

If the marginal cost of last unit produced is 50 what will be the elasticity of

demand for the product?

P = 70$ , MC = 50

P =MC/1+ (1/Ed) 70=50

We find “Ed”

P - MC = 1/Ed

70 – 50 = 1/Ed

20 = 1/Ed

Ed (20) = 1

Ed = 1/20

CS403 - Database Management Systems - GDB

"Normalization is a complex process but it’s a factor for successful database design" Justify this statement.

solution:

It is true normalization is a complex process and can be easily proved today’s most of RDBMs like SQL, Oracle etc are based on relation model like tables are connected to each other using primary and forgine keys.

As we know there are five normalization forms first three are often used.

In First normal form DBA has to identify the unique key for the entity identification.

It become more complex when DBA has to identify redundant information (columns) in an entity and create separate table to place this information in rows and build relation between them in Second Normal form.

It becomes even become more complex when DBA has to join two tables with the help of third table to build relation ship between two entities in third Normal form.

The purpose of all effort is to reduce data redundancy between tables, to centralize information and only capture entity related information. The benefit of this is increase of DBMS performance, better hardware resource management and data integrity.
