INTRODUCTION
•

Reason for research: The method FMT using to distribute the
textbooks and outlines to students is not as effective as we
expected.
•
Objective:
Instead of printing books for students , FMT can post the e-
books of all textbooks and outlines in the semester into the
faculty’s website
•
Research question:
•
Do FMT students find this method more
convenient?
•
Is this method work effective if we applied it?
•
For the FMT students who didn’t buy books
from FMT, will this new way bring the benefits
to them?
INTRODUCTION (cont)
METHODOLOGY
1. Population
425 FMT students course 08
374 FMT students course 09
799 students
2. Questionnaire
5 Y/N questions
3. Sample size and sampling method
n = 60
•

Random sampling method using Excel
=INT(RAND()*799)
•
Delivering questionnaire
METHODOLOGY (cont)
4. Data processing
Excel software was used to support the job
and calculate the complex statistics
5. Significant level
We chose α =5%.

HYPOTHESIS TEST
HYPOTHESIS TEST (cont)
•
Calculating the mean and standard
variance of sample
HYPOTHESIS TEST (cont)
Using z-test:
•
H
0:
µ = 860,000
•
H
a:
µ > 860,000
•
Significant level: α = 0.05

•
Decision rule: Critical value: z
0.05
≈ 1.645 Reject H
0
if z
>1.645
HYPOTHESIS TEST (cont)
•
The values of z
•
z = 3.385 > 1.96, we reject H
0
•
Conclusion: enough evidence to infer that the average
spending of students exceed the government’s subsidy
HYPOTHESIS TEST (cont)
1. Limitation
-
Unspecific answer
2. Implication
-
New policy
-
Financial management
PROJECT EVALUATION
1. Conclusion
-
Government’s subsidy is not enough
-

Get more from parents
2. Recommendation
-
Raising subsidy (if possible)
-
Getting more money from partime job
