ABSTRACT

This study was conducted to determine whether more than half of FSD students want to use Open Library or not. If the result supports this claim, buying this software may be considered. To perform the survey, from the population of all FSD students, a sample of 100 FSD students was chosen randomly to answer the questionnaire including 4 multiple choices. The data collected are used to perform the one sample z-test for a proportion which reveals that at 5% level of significance, more than 50% of respondents are willing to buy Open Library. For future research on this topic, it would be beneficial if this study is performed over a longer period of times with a larger sample size so that more extensive conclusions can be drawn.

1. INTRODUCTION

Open Library is an useful software that help students in accessing online information resources. After careful analysis, principal of Hanoi University believes that more than half of FSD students want to use it. Therefore, this project was carried out in order to determine whether the belief is true or not. In this survey, One hundred FSD students have been chosen randomly to answer the questionnaire in Open Library. If results of this research support principal‘s belief, this software is considered to be bought.

In terms of the statistic method, the one sample z-test for a proportion was taken to perform the survey. The null hypothesis is that the proportion of FSD students want to use Open Library equals 0.5 (H0: p = 0.5). The alternative hypothesis was simply that more than 50% of FSD students choose this software (Ha: p > 0.5).

As a result, the data reveals that the test statistic z came out to be 2.4, which is greater than z critical one tail (1.6449), meaning the null hypothesis is rejected. Therefore, there is enough evidendence to infer that the more than half of FSD students want to use Open Library.
