Question No.1
Write an inquiry letter, as a business person to the regional manager of Lahore of Nokia Company, and ask him to provide you all information about their company’s rules and regulations for opening a new franchise.
Question No.2
Write a short note on necessary steps for preparing an effective business message.
________________
The Process of Preparing Effective Business Message
PLANNING STEPS FOR COMMUNICATION
There are five planning steps:
1. Identify your purpose
2. Analyze your audience
3. Choose your ideas
4. Collect data to support your ideas
5. Organize your message
1. Identify your purpose :
You must know why you should write and what should be written . The purpose may be sale , good will , request , inquiry or refusal etc.
2. Analyze your audience :
It is better for the sender to understand the receiver. You should know his background , qualification , education , position , status in the company , desire , expectations , problems , circumstances and possible reactions to your request. Also he/she is superior , subordinate , laborer , professional or technical person , colleague , single or married , man or woman , young or old , new or long time customer .
3. Choose the ideas :
It depends upon the type of message . Before working jot down the points to be covered in communication , and then bring them in order of importance and urgency
4. Collect data to support your ideas
To explain facts and figures , visual aids may be utilized , augmenting the communication.
5. Organize ideas :
Once the ideas have been jotted down , they should be properly arranged and organized . Failing to organize will fail the objectives of the message .

STA301 Solution
Monday, November 16, 2009 Posted In STA Edit ThisQ No. 1 (a): In how many ways can 4 boys and 5 girls sit in a
row if every boy and girl has to sit side by side?
In order to fulfill the given condition, the seating arrangement must be as
follows.
GIRL BOY GIRL BOY GIRL BOY GIRL BOY GIRL
5 girls can seat in 5 × 4 × 3 × 2 × 1 = 120 ways
4 boys can seat in 4 × 3 × 2 × 1 = 24 ways
Total number of ways in which 5 girls and 4 boys can sit fulfilling the
given condition = 120 × 24 = 2880
Q No. 1 (b): Briefly explain the terms mutually exclusive
events, exhaustive events and sample space.
Mutually Exclusive Events: Those events that cannot occur at the same
time.
Example: When we toss the coin, we get either Heads or Tails but not both.
Exhaustive Events: Events are said to be collectively exhaustive, when the union of mutually exclusive events is the entire sample space.
Example: When we toss a coin, then Heads and Tails are collectively known as Exhaustive Events.
Sample Space: Sample Space is a set which consists of all possible outcomes resulting from a random experiment
Example: Sample Space in case of a fair die is S = {1,2,3,4,5,6}
Q No. 1 (c): A fair coin is tossed. Make a sample space and find
the probability of the followings:
I. One head appears
II. One tail appears
III. No head appears
The sample space for a toss is S = {Heads, Tails}
One head appears = . = 0.5
One tail appears = . = 0.5
No head appears = . = 0.5
Q No. 2 (a): In a simple linear regression yˆ = a + bx , interpret the
coefficients “a” and “b”.
a is called the y-intercept, and b indicates the rate of change in y with
respect to x and is formally known as the slope of the line.
Q No. 2 (b): A computer while computing the correlation
coefficient between two variables x and y from 25 pairs of
observations, obtained the following results:
n = 25 , Σx = 125 , Σx2 = 650 , Σy = 100 , Σy2 = 460 , Σxy = 508
It was, however discovered at the time of re-checking that it
had mistakenly copied down two pairs of observations as
below:
x y
11 10
9 7
While the correct values were
x y
14 8
12 9
Now find out the correct value of correlation coefficient
between x and y.
Correct Σx = 125 – 11 – 9 + 14 + 12 = 131
Correct Σy = 100 – 10 – 7 + 8 + 9 = 100
Correct Σx2 = 650 – 112 – 92 + 142 + 122 = 788
Correct Σy2 = 460 – 102 – 72 + 82 + 92 = 456
Correct Σxy = 508 – (11 × 10) – (9 × 7) + (14 × 8) + (12 × 9) = 555
= 0.41

Monday, November 16, 2009 Posted In CS and IT Edit ThisHubs, switches, and routers are all devices that let you connect one or more computers to other computers, networked devices, or to other networks. Each has two or more connectors called ports into which you plug in the cables to make the connection. Varying degrees of magic happen inside the device, and therein lies the difference. I often see the terms misused so let's clarify what each one really means.
A hub is typically the least expensive, least intelligent, and least complicated of the three. Its job is very simple: anything that comes in one port is sent out to the others. That's it. Every computer connected to the hub "sees" everything that every other computer on the hub sees. The hub itself is blissfully ignorant of the data being transmitted. For years, simple hubs have been quick and easy ways to connect computers in small networks.
A switch does essentially what a hub does but more efficiently. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others. The net result of using a switch over a hub is that most of the network traffic only goes where it needs to rather than to every port. On busy networks this can make the network significantly faster.
A router is the smartest and most complicated of the bunch. Routers come in all shapes and sizes from the small four-port broadband routers that are very popular right now to the large industrial strength devices that drive the internet itself. A simple way to think of a router is as a computer that can be programmed to understand, possibly manipulate, and route the data its being asked to handle. For example, broadband routers include the ability to "hide" computers behind a type of firewall which involves slightly modifying the packets of network traffic as they traverse the device. All routers include some kind of user interface for configuring how the router will treat traffic. The really large routers include the equivalent of a full-blown programming language to describe how they should operate as well as the ability to communicate with other routers to describe or determine the best way to get network traffic from point A to point B.
A quick note on one other thing that you'll often see mentioned with these devices and that's network speed. Most devices now are capable of both 10mps (10 mega-bits, or million bits, per second) as well as 100mbs and will automatically detect the speed. If the device is labeled with only one speed then it will only be able to communicate with devices that also support that speed. 1000mbs or "gigabit" devices are starting to slowly become more common as well. Similarly many devices now also include 802.11b or 802.11g wireless transmitters that simply act like additional ports to the device.
