INTRODUCTION
BANTUAN KHAS AWAL PERSEKOLAHAN 1 MALAYSIA
On 25 October 2013, the Prime Minister cum Finance Minister, Datuk Seri Najib Tun Razak
has approved an allocation of RM540 million for Bantuan Khas Awal Persekolahan 1
Malaysia while presenting the Budget Year 2014.All students from Year 1 to Form 5 for
2014 school session will receive RM 100 each. The purpose of the aid is to lighten the
financial burden of the students parents. Therefore, students are asked to prepare an
additional mathematics project by using statistics, linear law and mathematics reasoning to
perform the governments plan.
The History of statistics can be said to start around 1749 although, over time, there
have been changes to the interpretation of the word statistics . In early times, the meaning was
restricted to information about states. This was later extended to include all collections of
information of all types, and later still it was extended to include the analysis and
interpretation of such data. In modern terms, "statistics" means both sets of collected
information, as in national accounts and temperature records, and analytical work which
requires statistical inference. Statistical activities are often associated with models expressed using probabilities,
and require probability theory for them to be put on a firm theoretical basis: see History of
probability.
A number of statistical concepts have had an important impact on a wide range of
sciences. These include the design of experiments and approaches to statistical inference such
as Bayesian inference, each of which can be considered to have their own sequence in the
development of the ideas underlying modern statistics.
There has three methods to represent the statistics which are histogram, frequency
polygon and orgive.

Histogram is a graphical display of data using bars of different heights.
Example of histogram;
Frequency polygon, line graph is a drawn by joining all the midpoints of the top ofthe bars of a histogram.
Example of frequency polygon;
The graph of the cumulative frequency distribution is better known as cumulative
frequency curve or Ogive.

PART A
a) As a student receiving such aid, I will divide the money into a few parts. I will save 30% of the moneyin the bank that is RM30. I will spend 40% of the money as on education. I will use this RM 40 wisely
by buying reference books, exercise books, stationery and etc. I will use 10% of the aid given forentertainment. Another 20% that is RM 20, will be used to pay my tuition Photostat fees. The piechart below showed the ways I spent the aid.
b) Data on the amount of savings from 40 pupils of 5ST class receiving the Bantuan Khas AwalPersekolahan 1 Malaysia.

f. The final answer is RM13974.00.
Discuss of my findings above :
After my calculation, I find out the amount of the total savings after 10 years with assumptionthat no additional deposit is done in the both banks are totally different. By using formulaand Microsoft Excel, the amount of total savings after 10 years in Bank X is about RM1146.39 while the amount of total savings after 10 years in Bank Y is about RM13974.14.Obviously, the total savings after 10 years in Bank Y is more than Bank X. The difference
between the total savings of both banks is about RM12827.75.
If I save the whole amount of the aid, RM100, in Bank Y, I can earn RM13874.14 as interestafter 10 years. But I can only earn RM1046.3879 as interest after 10 years if I save theRM100 in Bank X.Therefore, I prefer to save the RM100 in the Bank Y because I can earnmore interest in Bank Y compare to Bank X.

that is xy acts as y-axis and x 2 acts as x-axis. Besides, I also find that the graph in (a) is not in linear graph
because a straight line cannot be obtained by joining all the point on the graph. While, the graph in (b) is
in linear graph because a straight line of the best fit is obtained by joining up all the point on the graph. In
addition, I can calculate the value of k and p in the equation through the graph in (b) but not the graph in(a).

From the equation of the graph in (b), I find that k is the gradient of the graph and p is a part ofthe y-intercept of the graph .

COMMENTS:
I would like to choose the savings plan offered by RHB Bank. It is because RHB Bank offer
a higher interest rate (1.20% p.a.) compared to OCBC Bank which only offer (0.25% p.a.).
The welfare provided by RHB Bank is also more comparing to OCBC bank. It is because the
multi-tiered interest rates in the savings plan of RHB Bank are calculated daily and credited
half-yearly in June and December. I can also access ATM and cashless shopping via e-post
facility. It is also up-to-date, reliable, and competitive. It is also convenient in updating my
passbook automatically via the Passbook Update Machine. Therefore, I think the savings plan
offered by RHB bank is more economical and suitable for me.

CONCLUSION
In conclusion, we should use the aid given wisely. We should not spend them on
unimportant things. For example, use them to buy video games, watch movies and ect. With
that, we will not waste the aid given to us. The remaining can be put into the bank to earn the
profit given. We should be more clever to choose the correct bank with the most profitable
interest. We have to plan before new make any decision. By doing this, we will not be
cheated by the bankers.
It is important for us to save money. The most important reason we need to save is formedical expenses. This is sometimes covered by medical cards and employers but we always
need some spare cash for the things they don't cover or to pay the premiums. Savings also
help pay for the quality of the medical services we need.
Saving money helps us pay for our dream home without paying too much interest to
the bank. We could save from a young age and be surprised to see how much we have at the
end. We need to save to be able to afford a college education for ourselves and our futuregenerations. It helps us to get a better job.

REFLECTION
Throughout the project while I was conducting it, I learned many stuff. This includes
on usage of knowledge and ways to conduct the project. While I was conducting the project, I
collected information from the internet and regarding the savings. Besides, I manipulated my
knowledge in other fields such as accounting and economics in this research. However, the
most important this I have learnt from this project is to plan before we do something. In this
project, I was regarded as the student of receiving Bantuan Khas Awal Persekolahan
1Malaysia. I was required to explain how am I going to use this money so that it achieve the
government objectives.
Thus, planning is required and information was given. While planning, I made few
tables on total profit incurred, average interest rate per month and also annual profit. This has
taught me that a lot of work should be done such as consideration and provision for
repayment before making a savings. We must be able to save our money in bank which offer
higher profit and advantages and should not make decision in a haste because great haste make
great waste.
Besides, I learned how to cooperate with friends. My friends and I discussed about the
project and we shared ideas among ourselves. This discussion has made me more confident
when doing something. I also learned to be disciplined in terms of punctuality, doing project
and not least to avoid plagiarism.
In a nutshell, I have learned something about the future and how serious can it be
if we make a wrong decision. Moreover, work that we done must be original and not totally
derived from other people. These two images have expressed my opinions from this project.

Everything comes with a plan. Without a plan, we will fail. Just like the saying goes, wedont plan to fail but we fail to plan .
A perfectly good business plan is a must to be done to have a long-lasting andprofitable business.
