Trang 2• Introduction
• Research Methodology
• Descriptive Results and Findings
• Results and findings of hypothesis test
• Project Evaluation
• Conclusions and Recommendations
Trang 3• 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 texte-books and outlines in the semester into the
faculty’s website
Trang 4• 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?

• Approximation Method for grouped data:
HYPOTHESIS TEST
Trang 13HYPOTHESIS TEST (cont)
Trang 14• Calculating the mean and standard variance of sample
HYPOTHESIS TEST (cont)
Trang 15Using z-test:
• H0: = 860,000
• Ha: > 860,000
• Significant level: = 0.05
• Decision rule: Critical value: z0.05 1.645 Reject H0 if z
>1.645
HYPOTHESIS TEST (cont)
Trang 16• The values of z
• z = 3.385 > 1.96, we reject H0
• Conclusion: enough evidence to infer that the average spending of students exceed the government’s subsidy
